The Output Variables Tab

You can use the Output Variables tab (Figure 29.13) to add analysis variables to the data table. If you request a plot that uses one of the output variables, then that variable is automatically created even if you did not explicitly select the variable on the Output Variables tab.

The following list describes each output variable added to the data table and indicates how the output variable is named. represents the name of the classification variable.

Posterior probabilities of group membership

adds variables named CDAProb_, where is the name of an X variable.

Predicted groups

adds a variable named CDAPred_ that contains the name of the group to which each observation is assigned.

Canonical scores

adds variables named CDA_1 through CDA_, where is the number of canonical components.

If a classification fit plot is requested on the Plots tab, then a variable named CDALogProb_ is created, as described in the section "The Plots Tab".
