Purpose
GUI to select number of components from a PCA sum-of-squares captured table.
Synopsis
- ncomp = choosencomp(model)
Description
The input model can be a standard PCA model structure or just a sum-of-squares (SSQ) captured table from a PCA model. CHOOSENCOMP creates a GUI that displays the SSQ table and allows the user to select the number of principal components (ncomp) from the list.
The returned value, ncomp, is the number of selected components or an empty value [] if the user selected Cancel in the GUI.
