I have 15 cross-sections. Using numbers 1-14 in the order isn't working as I see that my predicted values do not match what SAS shows in out=dataset.</P></BODY></HTML> Tue, 21 Aug 2012 19:59:52 GMT https://communities.sas.com/t5/SAS-Procedures/PROC-PANEL-What-values-SAS-uses-for-the-cross-sectional-dummies/m-p/100696#M28316 gaussian 2012-08-21T19:59:52Z Re: PROC PANEL: What values SAS uses for the cross-sectional dummies in fixed-effects model? https://communities.sas.com/t5/SAS-Procedures/PROC-PANEL-What-values-SAS-uses-for-the-cross-sectional-dummies/m-p/100697#M28317 <HTML><HEAD></HEAD><BODY><P>I haven't experimented with PROC PANEL (and on a quick glance, the support documentation doesn't help me) but you may want to check whether it's using "effect coding".
