Thank you, Steve! Hisako -----Original Message----- From: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu] On Behalf Of sjsamuels@gmail.com Sent: Sunday, July 05, 2009 7:50 AM To: statalist@hsphsun2.harvard.edu Subject: Re: st: Evaluation of Logistic Regression of Complex Survey Data -- To plot the ROC curve, see:http://groups.google.de/group/statalistrss/browse_thread/thread/512f852d 8f66a711/2a20319878808e92 Roger Newson's -somersd- (downloadable from SSC) will compute and compare the areas under ROC curves with weighted, clustered data together. See caveats at: http://www.stata.com/statalist/archive/2007-06/msg00166.html To mimic Stata's -linktest-, see: http://www.stata.com/statalist/archive/2008-10/msg00882.html The original topic was about -svy: reg- . After logistic regression, make sure that you generate the linear predictor, not the probability with "predict yhat, xb" -Steve On Fri, Jul 3, 2009 at 11:52 AM, Hisako Kobayashi<hisakoko@usc.edu> wrote: > I am analyzing a logistic regression with svy command.
