Get the standard error from --exlogistic-- command?

[Chang Xu]

Hi all,

I'm running the exlogistic command for meta-analysis, with id as study id:

exlogistic r id group, binomial(n) group(id)

Exact logistic regression                    Number of obs     =        576
Group variable: __id                         Number of groups  =          8

Binomial variable: __n                       Obs per group:
                                                           min =         26
                                                           avg =       72.0
                                                           max =        197

                                             Model score       =    2.41637
                                             Pr >= score       =     0.1258
---------------------------------------------------------------------------
         __r | Odds Ratio       Suff.  2*Pr(Suff.)     [95% Conf. Interval]
-------------+-------------------------------------------------------------
     __group |   .5874346          23      0.1664       .279409    1.216778
---------------------------------------------------------------------------

How can I get the standard error of the log OR? See the following method cannot work.

gen se = _se[__group]

no variables defined
r(111);

Thanks
Chang

Chang, exlogistic stores SEs in a matrix e(se), not e(V) -- that's why _se doesn't work. After the estimation, you may run

mat list e(se)
gen se = e(se)[1,1]

Thanks Wang. A very good solution!
