The Partition red triangle menu options give you the ability to customize reports according to your needs. The available options are determined by the type of data that you use for your analysis.

Display Options

Contains options that show or hide report elements.

Show Points

Shows the points. For categorical responses, this option shows the points or colored panels.

Show Tree

Shows the large tree of partitions.

Show Graph

Shows the partition graph.

Show Split Bar

(Available only for categorical responses.) Shows the colored bars that indicate the split proportions in each leaf.

Show Split Stats

Shows the split statistics. For more information about the categorical split statistic G2, see Statistical Details for the Partition Platform.

Show Split Prob

(Available only for categorical responses.) Shows the Rate and Prob statistics in the node reports.

JMP automatically shows the Rate and Prob statistics when you select Show Split Count. For more information about Rate and Prob, see Statistical Details for the Partition Platform.

Show Split Count

(Available only for categorical responses.) Shows frequency counts in the node reports. When you select this option, JMP automatically selects Show Split Prob. And when you deselect Show Split Prob, the counts do not appear.

Show Split Candidates

Shows the Candidates report.

Sort Split Candidates

Sorts the Candidates reports by the statistic or the log(worth), whichever is appropriate.

Split Best

Splits the tree at the optimal split point. This is equivalent to clicking the Split button.

Prune Worst

Removes the terminal split that has the least discrimination ability. This is equivalent to clicking the Prune button.

Minimum Size Split

Define the minimum size split allowed by entering a number or a fractional portion of the total sample size. To specify a number, enter a value greater than or equal to 1. To specify a fraction of the sample size, enter a value less than 1. The default value is set to the maximum of 5, or the floor of the number of rows divided by 10,000.

Lock Columns

Interactively lock columns so that they are not considered for splitting. You can turn the display off or back on without affecting the individual locks.

Plot Actual by Predicted

(Available only for continuous responses.) Shows a plot of actual values by predicted values. See Actual by Predicted Plot.

Small Tree View

Shows a small version of the partition tree to the right of the partition plot.

Tree 3D

Shows a 3-D plot of the tree structure. To access this option, hold down the Shift key and click the red triangle menu.

Leaf Report

Shows the mean and count or rates for the bottom-level leaves of the report.

Column Contributions

Shows a report indicating each input column’s contribution to the fit. The report also shows how many times it defined a split and the total G2 or Sum of Squares attributed to that column.

Split History

Shows a plot of RSquare versus the number of splits. If you use excluded row validation, holdback validation, or a validation column, separate curves are drawn for training and validation RSquare values. The RSquare curve is blue for the training set and red for the validation set. If you select K Fold Crossvalidation, the RSquare curve for all of the data is blue, and the curve for the cross validation RSquare is green.

K Fold Crossvalidation

Shows a Crossvalidation report that gives fit statistics for both the training and folded sets. For more information about validation, see K-Fold Crossvalidation.

ROC Curve

(Available only for categorical responses.) Receiver Operating Characteristic (ROC) curves display the efficiency of a model’s fitted probabilities to sort the response levels. See ROC Curve.

Lift Curve

(Available only for categorical responses.) Lift curves display the predictive ability of a partition model. See Lift Curve.

Show Fit Details

(Appears only for categorical responses.) The Fit Details report shows several measures of fit and provides a Confusion Matrix report. See Show Fit Details.

Save Columns

Contains options for saving model and tree results, and creating SAS code.

Save Residuals

Saves the residual values from the model to the data table.

Save Predicteds

Saves the predicted values from the model to the data table.

Save Leaf Numbers

Saves the leaf numbers of the tree to a column in the data table.

Save Leaf Labels

Saves leaf labels of the tree to the data table. The labels document each branch that the row would trace along the tree. Each branch is separated by “&”. An example label might be: “size(Small,Medium)&size(Small)”. However, JMP does not include redundant information in the form of category labels that are repeated. A category label for a leaf might refer to an inclusive list of categories in a higher tree node. A caret (‘^”) appears where the tree node with redundant labels occurs. Therefore, “size(Small,Medium)&size(Small)” is presented as ^&size(Small).

Save Prediction Formula

Saves prediction formulas to a column or multiple columns in the data table. The formulas consist of nested conditional clauses that describe the tree structure. If the response is continuous, one column that contains a Predicting property is added. If the response is categorical, columns that contain a Response Probability property are added for each level of the response. In addition, a Most Likely column that contains the response level with the highest probability of occurrence for each observation is added.

Save Tolerant Prediction Formula

Saves a formula that predicts even when there are missing values and when Informative Missing has not been checked. The prediction formula tolerates missing values by randomly allocating response values for missing predictors to a split. If the response is continuous, the column contains a Predicting property. If the response is categorical, the column contains a Response Probability property. If you have checked Informative Missing, you can save the Tolerant Prediction Formula by holding the Shift key as you click the report’s red triangle.

Save Leaf Number Formula

Saves a column containing a formula in the data table that computes the leaf number.

Save Leaf Label Formula

Saves a column containing a formula in the data table that computes the leaf label.

Make SAS DATA Step

Creates SAS code for scoring a new data set.

Publish Prediction Formula

Creates a prediction formula and saves it as a formula column script in the Formula Depot platform. If a Formula Depot report is not open, this option creates a Formula Depot report. See Formula Depot.

Publish Tolerant Prediction Formula

Creates a tolerant prediction formula and saves it as a formula column script in the Formula Depot platform. If a Formula Depot report is not open, this option creates a Formula Depot report. See Formula Depot. If you have checked Informative Missing, you can use this option by holding the Shift key as you click the report’s red triangle.

Specify Profit Matrix

(Available only for categorical responses.) Enables you to specify profits or costs associated with correct or incorrect classification decisions. For a nominal response, you can specify the profit matrix entries using a probability threshold. See Show Fit Details.

Profiler

Shows an interactive profiler report. Changes in the factor values are reflected in the estimated classification probabilities. See Profiler in Profilers.

Color Points

(Available only for categorical responses.) Colors points based on their response level. This is equivalent to clicking the Color Points button. See Report for Categorical Responses.

See Redo Menus and Save Script Menus in Using JMP for more information about the following options:

Redo

Contains options that enable you to repeat or relaunch the analysis. In platforms that support the feature, the Automatic Recalc option immediately reflects the changes that you make to the data table in the corresponding report window.

Save Script

Contains options that enable you to save a script that reproduces the report to several destinations.

Save By-Group Script

Contains options that enable you to save a script that reproduces the platform report for all levels of a By variable to several destinations. Available only when a By variable is specified in the launch window.
