Function Summaries Options

The Function Summaries red triangle menu contains the following options:

Customize Function Summaries

Displays a window that enables you to select the number of FPCs and the summary statistics that are shown in the Function Summaries report. If the number of FPCs to be shown is specified, the Functional PCA report is also updated. There is also a check box, Save Graphs, that determines whether a graph for each function is included in the data table produced by the Save Summaries option.

Note: The maximum number of FPCs that can be specified for B-Spline, P-Spline, or Fourier models is 10. For Wavelet models or Direct Functional PCA, the maximum number of FPCs that can be specified is 20.

Tip: If you have multiple functional processes, you can customize all Function Summaries reports to show the same summary values by clicking Ctrl and selecting Customize Function Summaries.

Save Summaries

Saves the summary statistics specified in the Function Summaries report to a new data table. The name of the new data table describes the model fit. This data table contains formula columns for the eigenfunctions, mean function, prediction function, and conditional prediction function. If the Save Graphs option is selected in the Customize Function Summaries window, there is also a column that contains the image of a graph of the raw data and the specified model fit for each function. In the data table, there is a profiler script that launches the prediction profilers for the prediction and conditional prediction formulas. These formulas are functions of the input variable, the ID variable, and the eigenfunctions.

Tip: For Wavelet models, the wavelet coefficients are also saved to the data table that is created using the Save Summaries option.

Control Chart Builder

Analyzes the functional principal components using the Control Chart Builder. An individual chart and Limit Summaries table is created for each functional principal component in the Function Summaries table. See “Control Chart Builder” in Quality and Process Methods.
