Hi John!

Full ACK with Helmut's suggestion. Seems he has basic SAS speak knowledge acquired :cool:

.
If you set the values of one treatment just to missing SAS nevertheless tries to estimate the treatment effect for it with is of course missing. Result: Errors.

Also full ACK with the estimate statement. After removing one treatment it has only two entries.

BTW: Be careful with this estimate. The factors +1, -1 and zero depend on the coding of our treatment factor. It's lexicographic. T1, T2 come after R if you have coded as usual T1, T2, R.
