The dependent variable is the difference between pre and post values which is continuous, and the covariates are mixed. I will appreciate a sample code, thanks.</P><P>&nbsp;</P><P>Epiguy</P> Fri, 21 Dec 2018 20:23:01 GMT Epiguy 2018-12-21T20:23:01Z https://communities.sas.com/t5/SAS-Programming/means-regression-analysis/m-p/523168#M142126 <P>How to code and run a regression on mean or median of calculated variables to predict what accounts for differences between pre and post measurements.
