I'm wondering if someone could write a procedure to summarize lognormal data automatically in the form of geometric mean and std etc. It's easy to transform data to get the results, but it would be nice if it's automated. The means commands (gmeans or ameans) do not give standard deviation.

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/ > -- Junlin * * 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/
