QUESTION;
I need to calculate confidence interval and difference with proc genmod
Thanks.
The confidence interval and difference of what?
As a start, refer to the PROC GENMOD Documentation Example Section.
Assuming that you want to compare the means of your two treatments on some response variable, Y, you can use the NLMeans macro following the fit of your model in PROC GENMOD. See the examples in the Results tab of the NLMeans macro documentation. However, if your response is normally distributed, you can simply use PROC GLM and its MEANS statement instead of GENMOD and the NLMeans macro.
