Dear Stata Guru's,

I want to compute geometric mean and SD from survey data. Here is an example:

. svy:mean  lnbenz,over (sex)
(running mean on estimation sample)

Survey: Mean estimation

Number of strata =      13          Number of obs    =     647 Number
of PSUs   =      27          Population size  = 1.5e+08
                                    Design df        =      14

    _subpop_1: sex = 0. Male
    _subpop_2: sex = 1. Female

--------------------------------------------------------------
             |             Linearized
        Over |       Mean   Std. Err.     [95% Conf. Interval]
-------------+------------------------------------------------
lnbenz       |
   _subpop_1 |   .3884244   .2993531     -.2536241    1.030473
   _subpop_2 |   .1070038   .1907388     -.3020902    .5160979
--------------------------------------------------------------

I can manually type
Di exp(0.3884244)

For each of the category but I have to type hundreds of time since I
have several variables. I tried egenmore option but I couldn't find
how to use it with svy command. Can any help point me to the resource
to find more info? Is there program I can use to automate this
process? Ideally I would like Stata to run the survey command and then
use the mean value to compute geometric mean and SD. Any help will be
greatly appreciated

Thank you
Ahmed
