A TYPE=UCORR data set is almost identical to a TYPE=CORR data set, except that the correlations are uncorrected for the mean.
The corresponding value of the _TYPE_ variable is ’UCORR’ instead of ’CORR’. Uncorrected standard deviations are in observations with _TYPE_=’USTD’. A TYPE=UCORR data set can be used as input for every SAS/STAT procedure that uses a TYPE=CORR data set, except for
the CANDISC, DISCRIM, and STEPDISC procedures. TYPE=UCORR data sets can be created by the CANCORR, PRINCOMP, and VARCLUS procedures.
