Hi, I'm running a proc reg with a weight and needing U95 and L95 from that, actually using freq instead of weight, but never the less the issue I'm getting is if I'm using logged data in the model statement I get an equal range between U95 and L95 between observations, but when unlogged it's not equal.. If I was to use a norml (not-logged) in the model statement, I get an equal range from U95 to L95 between observations.. proc reg data = test; model DepPrice = Price1; freq counts; run; diff between U95 and L95 for all observations is 300 (some are 301 and 299, but very very close to eachother) if I had proc data = test; model Logged_DePPrice = Logged_Price1; freq counts; run; diff between U95 and L95 for all observations is 5.71, but when I unlog U95 and L95 and then find the difference between the 2 I get values such as 100, 234, etc.. various..which I'm assuming makes more sense. .. Any experience with this?  what makes most sense. Thanks ... View more
