Hi Nick, Many thanks for the advice - can I just check that I have substituted the glm command in the right way below? The adjusted means I am getting from the glm model seem different to what I would expect. xi:reg log_ins i.q5_adj age smoke bmi adjust age smoke bmi, by (q5_adj) se ci xi:glm ins i.q5_adj age smoke bmi, link(log) adjust age smoke bmi, by (q5_adj) se ci Many thanks, Best wishes, Amy ---------------------------------------- > Date: Tue, 16 Aug 2011 10:20:39 +0100 > Subject: Re: st: Log transformation > From: njcoxstata@gmail.com > To: statalist@hsphsun2.harvard.edu > > Why not start again with -glm, link(log)- which does this for you? > > Nick > > On Tue, Aug 16, 2011 at 9:54 AM, Amy Jennings <amyjennings79@hotmail.com> wrote: > > > I have run a regression model in stata with a continuous outcome, a categorical predictor and a number of covariates using xi:reg followed by the adjust command. > > > > My continuous outcome measure is log-transformed using the natual log is there any command for back-transforming the adjusted means and confidence intervals to the original units? > * > * For searches and help try: > * http://www.stata.com/help.cgi?search > * http://www.stata.com/support/statalist/faq > * http://www.ats.ucla.edu/stat/stata/ * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
