Model Driven Multivariate Control Chart Platform 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

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 components 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.

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.

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.
