If proc powerglm codes are fine, please share your output with me?  I face continue errors, not codes are not computed at all. ... View more

I think for understanding this model, I will explain more about it.  my main focus is to calculate a number of sample size using glmpower. I directly follow the SAS glmpower reference.  In terms of the reference, the limited info means by time and groups. I exactly follow the step as the reference indicated. however GLM doesnot produce f test results and proglm doesnot run with the sas codes indicate in the reference. I want to get multiple simulations using proc  powerglm but it doesnot produce any output, as well as code of 'repeated time' does not work( changed a red color).   can you share your idea in terms of glmpower not glm. thank you so much!!    ...
