Because the mean age of Group A is 10 years older than Group B, and score is correlated with age, I want to do the regression analysis with "age adjustment". Could anyone tell me which statistics I use and where I put those parameters for "age adjustment"?&nbsp;</P> Fri, 23 Sep 2016 00:04:10 GMT https://communities.sas.com/t5/Statistical-Procedures/Age-adjustment/m-p/300244#M15966 Kame77 2016-09-23T00:04:10Z https://communities.sas.com/t5/Statistical-Procedures/Age-adjustment/m-p/300252#M15967 I don't know, Maybe you could check UNIT statement.
