There is I believe some literature on ad hoc tests for this question, but the results of . findit lognormal do not show any Stata implementations. I'd recast the problem as one of estimating a model using either -glm, link(log) f(normal)- or -lognfit- (SSC). Nick n.j.cox@durham.ac.uk N.M.Postel-Vinay@lse.ac.uk Is there a test of differences between geometric means, assuming lognormal distributions? * * 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/
