MI was looking up information on another topic when I came across some ANOVA output from SPSS:
Source SS df MS F p eta2 Power
X1 0.08 1 0.08 0.02 0.90 0.0012 0.05
X2 etc
The interpretation of the output was, "X1 was not signficant (p=0.90), but the study lacked sufficient power in that test (0.05)."
I thought that would be very important information to have and would like to see it in my SAS output. I did some searching and found Proc GLMPOWER, but I don't think it is applicable.
Is there some other way to get the power associated with each variable in the ANOVA output?
(I'm using SAS 9.3)
SAS has a proc power but is really intended for use in study planning. Look to see if you have the SAS Power and Sample Size Analysis installed.
Also I am somewhat leery about assumptions that may be going into the ANOVA regarding the actual sample design to get the reported power.
