Have you used multivariate procedures in SAS and wanted to save out scores? Some procedures, such as FACTOR, CANDISC, CANCORR, PRINCOMP, and others have an OUT= option to save scores to the input data set. However, to score a new data set, or to perform scoring with multivariate procedures that do not have an OUT= option you need another way.
Scoring new data with these procedures is a snap if you know how to use PROC SCORE. The OUTSTAT data sets from these procedures includes scoring code that the procedure uses to score observations in the DATA= data set. They are contained in the observations where TYPE=’SCORE’.
The only catch, however, is that if you use a hierarchical method such as the VARCLUS procedure, then the score code is included for the 1-, 2-, 3-, and so on cluster solutions, up to the final number of clusters in the analysis. PROC SCORE doesn’t know which one to use.
So you have one extra (teeny-tiny) step to perform scoring:
