Why JMP? (PDF)
JMP statistical discovery software from SAS is the tool of choice for scientists, engineers and other data explorers in almost every industry and government sector. JMP combines powerful statistics with dynamic graphics, in memory and on the desktop. Interactive and visual, JMP reveals insights that raw tables of numbers or static graphs tend to hide.
Because everything is linked – the graphics, statistics and data – JMP encourages you to dig deeper and ask more questions, improving your chance of making breakthrough discoveries in your data. With JMP, analyses unfold, driven by what the data reveals at each step. You can explore your data without leaving the analysis flow or having to rerun commands as new questions arise.
JMP brings your data analysis to a whole new level, letting you tackle routine and difficult statistical problems more easily and communicate your findings more effectively.
JMP is my go-to tool for on-the-fly data analysis.

Your data comes in many forms. Fortunately for you, JMP is hungry for data.
Easily read from Microsoft Excel using the Excel Import Wizard, from text files using the Text Import Wizard, and pull data directly from ODBC-compliant databases using the interactive Query Builder. Whatever the format, JMP is ready.
Databases allow organizations to catalog massive amounts of data and information, but databases are usually organized for efficient storage and transactions, not for efficient analysis. This means that the data you need for analysis is scattered across multiple tables. You have to join those tables to assemble the data you need. This can make for significant work and require you to learn not only the details of the data tables, but also how to use SQL or other tools to join them.
Enter Query Builder. Using this JMP platform, you specify only the primary table and one or more secondary tables, and Query Builder automatically matches foreign keys in the primary table to primary keys in the secondary tables. So joining is no longer a laborious process – it becomes automatic.
And the best part of Query Builder is its interactivity; it requires no SQL coding. Combined with automatic matching, the tool has everything else you need to build your simple or complex query. No more delegating the work to an SQL expert or using multiple applications to access data and analyze data. Now, you can do it all with JMP.
In all cases, importing data into JMP is an interactive task, and the software reacts to changes you make during the process. So a file imported into a JMP table is preformatted and is as close as possible to analysis-ready, saving you time and effort.
Imagine having confidence that your statistical analysis tool can handle your data, no matter what its original form. That’s what JMP offers. Because data imported into JMP is in memory, it doesn't matter where the data comes from. JMP tables are always fast, optimized to perform analytics, and ready for you to explore, while preserving as much of the structure and metadata of the original source as possible.
How much time do you spend preparing your data for analysis? For many data analysts this is a constant chore. JMP has long respected this fact and worked to make data preparation easier, faster and more reliable.
No matter what your data cleaning tasks, JMP automates the process. What is hard or even impossible in other software is easy in JMP. And even if you can't clean your data directly, JMP includes methods to minimize the impact of data problems on your analysis, often eliminating the need (and effort required) to make your data pristine.
Once your data resides in a JMP table, you can take advantage of the JMP Tables menu, which is rich with reshaping and restructuring tools, such as Stack, Split, Transpose and Summary. When you want to merge all of your data into a single file, you can easily perform intelligent and interactive table joins.
Before you begin analyzing your data, you should check to make sure it is clean, that the values are consistent and encoded well. JMP offers many ways to do this. One of the best is with the Distribution platform. If you spot outliers, simply grab them and they are selected in the table, thanks to dynamic linking in JMP.
Having a visual interface to your data is a powerful advantage of JMP. You will soon wonder how much you were missing before you were able to immediately grab what you see in your data.
When many different individuals enter categories, naming can become inconsistent. To accurately tabulate the categories and use them for prediction, they must match up consistently. JMP has a Recode utility to make consolidation of categories easy rather than time-consuming. You can select a set of categories and choose which of them to make representative of the group. You can also tell JMP to automatically consolidate categories that look very similar to each other. This uses the concept of edit distance to do the matching and can be an incredible time saver, especially when the number of unique entries reaches into the hundreds or thousands.
Other tools for data cleanup in JMP include:
Spreadsheets don't easily reveal patterns and trends in data sets, yet seeing patterns helps you make discoveries. Some statistical analysis packages make you pay an upfront cost and force you to choose a particular graph without first letting you see how that graph might represent your data. You find yourself locked into the choices you made in the graph launch, unable to adapt to what you see without recreating the graph from scratch.
JMP frees you from the narrow path. Explore your data dynamically and allow your data to tell you what is interesting. Move through your data quickly and with agility until you find the visualization that best communicates the story in your data.
Graph Builder is the best way to begin exploring your data and graphing it dynamically. Interactively build simple or complex graphical displays, including polygon region maps, just by dragging and dropping. Simply drag the variables into position, choose the graph element from an icon palette, and customize the display to get your final, publication-quality result. Graph Builder always gives you options that make sense for your situation. Along with its great flexibility, JMP encourages you to make graphics that are sensible.
Graph Builder is only one of the many rich and dynamic visualization tools in JMP that make statistical discovery easier and more effective.
You can also add background maps to all relevant JMP graphs using high-quality, built-in geographic images, or plot data on street-level maps that include cities, roads and bodies of water. With Bubble Plot, you can create animated data movies, showing changes in many dimensions over time.
Graphs in JMP represent an interface to your data, not just a representation of it.
Employing basic tools for visual analysis is often the best way to communicate results and motivate action in an organization. And frequently, your first step in a statistical data inquiry consists of investigating variables one at a time, a process known as univariate analysis. In JMP, once you've identified the columns that interest you, the Distribution platform automatically provides graphs and statistics based on the variable's defined modeling type.
Quickly get histograms, summary statistics, box plots and quantiles for continuous data, capability analysis, distribution fitting and frequencies for nominal or ordinal values.
In any business, the quicker you can learn and adapt to ever-changing customer needs, the quicker you can get ahead of your competition. To accelerate this learning cycle, you need to be able to notice patterns in your data, focus on the most important, and act quickly. You can’t waste time generating a stack of reports to wade through, or worse, writing custom code and waiting for output before acting.
JMP brings a radically different approach to the daily task of slicing and dicing data. Its grouping and filtering paradigm allows for instant, in-memory recasting of report output. Imagine how quickly you can focus on interesting areas when you can update reports on the fly just by clicking through levels of a categorical variable. With one click, you can even switch the analysis focus to a new metric entirely.
Many organizations rely on “A-B testing” for experimental design, but testing one situation against another with many factors in flux is a very slow way to learn about your business.
In contrast, design of experiments (DOE) in JMP offers a proven and practical approach for exploring and exploiting the multifactor opportunities that exist in almost all real-world situations. Using multifactor experiments, you learn more quickly, at minimal cost, by teasing out not just the effect of an individual factor, but also the combined impact of two or more factors. JMP offers leading-edge capabilities for design of experiments, so you can design the best experiments to answer specific questions. JMP also offers a rich set of analyses tailored to your design in a form you can easily use.
Instead of fitting your problem to a textbook design, you fit the design to your problem with the budget you have. The unique Custom Designer constructs an optimal design to fit your problem, taking into account specific conditions such as time, budget and other experimental constraints.
Many analysis problems include hard-to-change variables, such as the temperature of a reaction vessel or the location of a cornfield. A completely randomized design would require such factors to be reset after each experimental run, which is clearly impractical or cost-prohibitive. The design most appropriate in such situations is a split plot, and JMP can generate I-optimal split-plot, split-split-plot and strip-plot designs. JMP also includes the correct random-effect restricted maximum likelihood (REML) model in the table that contains the experimental worksheet to make the analysis rigorous but also straightforward. No other commercial software package offers this level of flexibility with split-plot designs.
In addition to Custom Designer, JMP also supports classical (textbook) full factorial, screening (fractional factorial), block, response surface, nonlinear and mixture designs, as well as advanced designs, including accelerated life tests and designs for computer simulation, such as cluster-based, space-filling designs that allow for inequality constraints on factors.
Also, JMP is the first software package to implement definitive screening designs. The most important new class of designs in the past 20 years, definitive screening designs are used to efficiently and reliably separate the vital few factors that have a substantial effect from the trivial many that have negligible impact. Definitive screening designs allow you to get information about main effects, curvature effects and two-way interactions at the same cost as traditional, two-level screening designs.
Who would ever do it the old way?
By making a useful separation of data into signal and noise, statistical models encapsulate trends and patterns so you can better learn about your business, your competition and your customers. This knowledge empowers you to take the best course of action and grow your business more easily.
Building useful models is part science and part art, and JMP includes an array of statistical platforms to help you build useful models of your data. With methods for revealing relationships among variables in a process, JMP allows you to not only make predictions but also to identify settings for factors that yield the best performance. JMP includes a variety of ways to fit linear and nonlinear models, and these diverse fitting tools help you make correct decisions, whatever relationships your data shows.
At the heart of the JMP model-fitting toolkit is the Fit Model platform. Fit Model lets you construct model terms and select from different methods, including standard least squares fitting, stepwise and all possible models. Build models with drag-and-drop ease using interactive model editing. You can also build other models, such as MANOVA, repeated measures, generalized linear, loglinear variance or logistic regression (nominal and ordinal).
JMP also fits mixed models with random effects using REML and includes advanced multivariate modeling techniques: principal components, multiple correspondence analysis, partial least squares, cluster, item analysis, partition models and more.
The Fit Y by X platform is intended for modeling dependencies between a single input and a single response or outcome. This platform supports simple linear regression, logistic regression, ANOVA, ANOM and contingency analyses. It responds to the modeling types of the variables used, and so unifies many commonly used methods if you don't need the control that Fit Model offers.
Too often, extracting meaningful conclusions from messy data entails the arduous process of exploring one variable or response at a time to find the key drivers. And when your data has missing values or outliers, you can easily find yourself in trouble.
JMP helps you build models with many columns by providing automated options for change when facing thousands of Y's with respect to a single X. Modern significance adjustment techniques – such as the false discovery rate – help you draw useful conclusions.
The JMP Nonlinear platform allows you to fit a large number of models to your data. The software's built-in library makes it particularly simple to fit popular bioassay and pharmacokinetic models. By defining appropriate formula columns, you can fit virtually any nonlinear model.
Advanced model-fitting capabilities in JMP include neural network models (the Neural platform) and decision trees (the Partition platform).
No matter what modeling techniques your data requires, you can quickly and easily build useful models in JMP.
Building models is useless unless you can motivate change. JMP lets you communicate model results and perform what-if or scenario analysis visually to understand the pattern of predicted response and how each factor affects it. In JMP, you explore this response surface visually through the Profiler, a dynamic tool for interacting with your model no matter how it was built. The Profiler lets you view the effect of a factor on the predicted response and shows a cross-section of the response surface.
Preventing failure and improving warranty performance are two of the most important reasons for using proven techniques to fully understand the performance of your products over time. JMP helps you pinpoint defects in materials or processes; it also helps identify design vulnerabilities so you can understand how best to correct them.
Do you need to determine the most appropriate distribution to use for making reliability lifetime predictions on your products and components? Let JMP automatically evaluate a large range of reliability distributions to find the best fit. Using Life Distribution analysis in JMP, you can specify a nonparametric distribution as well as numerous parametric distributions and compare fits visually.
The market demands continual improvement, which is why you strive to accelerate time to market, protect your brand by minimizing customer complaints, and deliver products and services that consistently meet or exceed customer expectations. JMP has the necessary tools to be at the heart of your quality program, providing a wide range of relevant graphical and statistical capabilities.
You can monitor processes with the full set of control chart types in JMP or build control charts interactively with drag-and-drop tools in the unique Control Chart Builder. With a workflow analogous to Graph Builder, Control Chart Builder lets you perform what-if analyses with your process data and explore many subgroup and phase variables and their effects on your processes. You see problems in ways that are impossible using static control charts.
The Measurement Systems Analysis platform supports multiple analysis methods, including Donald J. Wheeler's Evaluating the Measurement Process (EMP). Other quality analysis features in the software include provisions to perform Gauge R&R studies and create Pareto charts. You can easily visualize sources of variation in your measurement process, evaluate product defects, and monitor processes for stability. JMP also lets you investigate out-of-control conditions and perform root-cause analysis.
No matter what role you play in the process, marketing is complex and rapidly evolving, driven by the influx of digital technologies. Yet key business issues endure: the need to find the most profitable growth opportunities, develop the best products and services, take the best marketing action and maximize cross-business impact. To stay competitive, you need to socialize your brand, listen to customer feedback and then adapt your products and services. Whether you are conducting exploratory, descriptive or causal research using primary or secondary sources, JMP provides a comprehensive repertoire of tools for quickly and easily getting value from metric and nonmetric quantitative data.
No matter what your level of statistical expertise, JMP will help you find new consumer insights more quickly and allow you to communicate findings to other stakeholders to drive consensus and action.
Once you have completed your sophisticated analyses, employing basic tools for visual analysis is often the best way to communicate results and motivate action. The interactivity of JMP gives you the tools to share the meaning in graphs and not just the graphs themselves, so you clearly communicate complicated results.
The Profiler, for example, lets you share the meaning of your models in ways that become immediately interpretable and useful. The person viewing your graphics in JMP knows what is in your data, and can ask questions and gain a deeper understanding of your findings and your models. It’s easier to see the value of your data – and make the best decisions for your organization.
You can combine multiple windows – for example, a linked histogram, a graph with a map and a box plot – into an instant application dashboard that lets your audience focus on your findings, not on the task of navigating through slides or a static report.
To communicate findings to people outside of JMP, your options are equally diverse. Share JMP visualizations to Graph Builder for the iPad® and explore them on the go. Generate PowerPoint presentations in a single click, or generate interactive output of many JMP reports that can be viewed quickly in any device with a browser. JMP can also create presentation- or publication-ready graphics in a multitude of file formats.
Buying software that cannot grow beyond your initial needs leads to early obsolescence and expensive replacements. JMP includes many basic and advanced ways to mass-customize, even extend the software to address the unique challenges that arise as usage grows and your organization evolves.
The rich JMP Scripting Language (JSL) lets you work interactively and save results for reuse. Power users can develop new functionality to solve problems that core JMP does not address. These custom scripts can even integrate capabilities from other applications.
Use Instant-App tools in Application Builder to create custom displays from multiple reports and graphs in a drag-and-drop interface. Application Builder’s design-time development environment also lets you create complex analytic applications by simply dragging and dropping. And when you finish your custom application, deploy it to other JMP users in your organization with the easy-to-use Add-In Builder.
After writing scripts, use the full-featured JSL debugger to step through each line of code, interactively examining variables to determine what might be preventing a script from performing its intended function. Use the JSL Profiler to fine-tune a script’s performance by monitoring the time it takes to complete each step of a routine and iteratively optimize your code for peak efficiency and speed.
It's easier to work productively if you can configure your software to work the way you think. Consistent settings, graph output and even color palettes mean fewer steps to understanding data. JMP gives you a comprehensive set of preferences that enable you to control fonts, graphic options and detailed settings within platforms. JMP will work the way you work if you set it up that way. It's analysis the way you like it. With JMP, you can choose to display only those analytic tools and menus you use routinely. In fact, you can customize every aspect of JMP, including:
As a member of the SAS family, JMP offers a seamless interface to the unparalleled capabilities of SAS. The deep analytics, reporting and data management capabilities of SAS extend capabilities of JMP desktop software to the server and beyond. You can also use JMP with other analytic tools, including a full interface to the power of MATLAB, complete calling interface to DLLs and the rich set of specialized libraries in R. JMP makes it easy to reach out to these resources and bring back results for dynamic data visualization and analysis. Or you can seamlessly integrate an algorithm or function into the JMP workflow, making SAS, MATLAB or R feel like part of JMP.
Does your data live in spreadsheets? With the JMP add-in for Microsoft Excel, you can easily move data from Excel into JMP or bring the power of the Profiler for JMP to your spreadsheet models, enhancing the data with the advantages of JMP visualization.
