RPCA Procedure

The ID statement lists one or more variables to be copied from the input data table to the OUTLOWRANK=, OUTSPARSE=, OUTERROR=, PCSCORES=, and SVDLEFT= output data tables, and to the file that is specified in the RSTORE= option in the SAVESTATE statement. If any of the variables in the ID statement appears in the INPUT statement, that variable is considered to be an ID variable and is not used in the analysis (it is only copied to the output tables and the file that you specify in the RSTORE= option).
