Thanks, Dale!
I had tried that, but got results that did not make sense.
The missing piece was that I had forgotten to specify ML, which, as you point out, makes all the difference.
Much chagrined, and grateful...

Thanks - the CONTRAST statement worked - I had only used this with group means (and examples also only use class variables), so did not think it could be applied to continuous variables.
Dangers of ASSUMING! - thanks again!

Is there a way to get (or calculate) formal test for set of predictors controlling for other model variables in PROC MIXED?
Similar to the TEST statement in PROC REG.
For example, I'd like to test contribution of set of 3 psychological variables after controlling for 3 anthropometirc variables in a mixed model.
Thanks!
