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.

Highlight one or more variables. To highlight multiple variables at once, hold down
