I am working on a project using Stata 15.1 using survey data with a complex design, that also involves analyzing biochemical data.

I tried to use this commands to get geometric mean and sd, but they are not working.

svy: mean <variable>, over(variable2)
ereturn display, eform (geo_mean).

The "ereturn display" command simply returns the same value I get with the original svy command. I cannot find any information.
Any assistance anyone could offer would be really appreciated.

Thanks,
Sara
