Use this field to specify the character or numeric variables for which to construct principal components. Each distinct level of these class variables is used to construct a numerical column of 0s and 1s in the analysis.
Caution: Specifying a very large number of variables or using a data set with a large number of variables can prohibitively increase the time needed to run this process.
All of the variables in the input data set are displayed in the Available Variables field.
