Model Driven Multivariate Control Chart Platform Options

The PCA Model Driven Multivariate Control Chart red triangle menu contains the following options:

Show History Summary Statistics

Shows or hides summary statistics for rows designated as historical data or all rows if historical data rows are not specified. Summary statistics include univariate means and standard deviations for process variables. For PCA-based charts, the eigenvalues and eigenvectors are displayed. For charts based on PLS scores, the standard deviation of scores and the score loadings are displayed.

Monitor the Process

Contains the following options for monitoring the process.

Show Monitoring Plots

Shows or hides the selected process monitoring plots.

Set Component

Enables you to set the number of components for the T2, DModX, or SPE plots. The number of components can range from one up to the number of valid eigenvectors for PCA driven analysis or from one up to the number of PLS model factors for PLS driven analysis.

Set α Level

Enables you to adjust the alpha level that is used for all control chart limits.

T2 Plot

Shows or hides a T2 plot. The T2 statistic is a summary of multivariate variation that measures how far away an observation is from the center of a PCA or PLS model.

Note: When using local data filters with historical data, T2 charts are only available for groups with historical data.

Normalized DModX Plot

Shows or hides a plot of the normalized DModX values. DModX measures the distance of each observation to the PCA or PLS model. A high DModX value indicates an observation that deviates from the underlying correlation structure of the data.

Squared Prediction Error Plot

Shows or hides the squared prediction error (SPE) plot. SPE measures the sum of squared of the residuals from the PCA or PLS model. A high SPE value indicates an observation that deviates from the underlying correlation structure of the data.

Score Plot

Shows or hides a score plot of principal components or partial least squares factors. See Score Plot.

Diagnose the Process

(Available when at least one diagnostic plot is active.) Shows or hides diagnostic plots.

Show Excluded Rows

Shows or hides excluded rows on plots (excluded rows shown by default). When this option is selected, excluded rows are displayed and included in the count of out of control points. However, excluded rows are excluded from numerical calculations. Rows that are both hidden and excluded in the data table remain hidden on MDMVCC plots regardless of the Show Excluded Rows setting.

Note: Control charts launched from MDMVCC show or hide excluded rows based on the Show Excluded Rows setting.

See Redo Menus in JMP Reports, Save Platform Preferences, and Save Script Menus in JMP Reports 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.

Platform Preferences

Contains options that enable you to view the current platform preferences or update the platform preferences to match the settings in the current JMP report.

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.
