Partial eta squared using SAS PROC MIXED

I am trying to obtain partial eta squared values, as a journal is asking for this. I used SAS PROC MIXED and have not been able to find anything about this. Does anyone know of a way to do this, or a round about way?

Re: Partial eta squared using SAS PROC MIXED

I wonder if this can be done, as partial eta squared values are usually calculated using sums of squares.  One approach would be to calculate the noncentral F value, and then apply (partial eta squared) = (noncentral F value)/(noncentral F value + number of observations).  I got this formula from the documentation for the GLM procedure.  There are also formulas for a variety of estimators of the noncentral F.

Hope this helps.
