STDDEV and CORR Records (DISCRIMINANT command)

Records written with ROWTYPE_ values STDDEV and CORR are influenced by specifications on the STATISTICS and CLASSIFY subcommands.

• If BOXM or GCOV is specified on STATISTICS or SEPARATE is specified on CLASSIFY, the STDDEV and CORR records represent within-cell data and receive values for the grouping variable.
• If none of the above specifications is in effect, the STDDEV and CORR records represent pooled values. The STDDEV vector contains the square root of the mean square error for each variable, and STDDEV and CORR records receive the system-missing value for the grouping variable.
