A TYPE=UCOV data set is similar to a TYPE=COV data set, except that the covariances are uncorrected for the mean. Also, the corresponding value of the _TYPE_ variable is ’UCOV’ instead of ’COV’. A TYPE=UCOV data set can be used as input for every SAS/STAT procedure that uses a TYPE=COV data set, except for the CANDISC, DISCRIM, and STEPDISC procedures. TYPE=UCOV data sets can be created by the CALIS and PRINCOMP procedures.
