Problem Note 32395: Wrong numbers from ONECORR or MULTREG statement in PROC POWER
 |  |  |  |  |
When running PROC POWER with the ONECORR or the MULTREG statement, you might obtain incorrect results in specific instances.
*
For software releases that are not yet generally available, the Fixed
Release is the software release in which the problem is planned to be
fixed.
If you use the ONECORR statement and specify a high correlation, a null correlation value of 0, and a small sample size using a t distribution, the calculated power will be incorrect.
Using a t distribution with NTESTPREDICTORS=1 and METHOD=RANDOM and SIDES=2 on the ONECORR statement is equivalent to using the MULTREG statement. Therefore, the MULTREG statement might give the same incorrect results when implementing a design that combines a high correlation and a small sample size.
You will not see any errors or warnings in the log.
