The CERTSIZE option for specifying the certainty size measure is now available for METHOD=PPS_SYS and METHOD=PPS_WR. You can now specify the interval and start values for METHOD=SYS and METHOD=PPS_SYS.

The GROUPS= option requests random assignment of the observations in the input data set to groups. You can specify the total number of groups as n, which must be a positive integer. Or you can provide a list of group size values, which are positive integers that specify the number of observations in the groups.
