RE: st: Output logistic regression results using outreg

Thank you very much.
The following worked:
Logistic exa_dif1 absch_total
outreg using results, stats(b ci p) varlabels replace
--------------------------------------------
exa_dif1 absch_tot 0.008
(-0.013 - 0.029)
[0.44]
Constant -1.454
(-1.738 - -1.169)**
[0.00]
N 342
--------------------------------------------
* p<0.05; ** p<0.01
In order to get OR instead of beta:
. outreg using results, stats(e_b e_ci p) varlabels replace
----------------------------------------
exa_dif1 absch_tot 1.008
(0.987 - 1.030)
[0.44]
N 342
----------------------------------------
* p<0.05; ** p<0.01
In order to append results, the following worked:
Logistic exa_dif1 absch_total treat
outreg using results, stats(e_b e_ci p) varlabels merge replace

Hi,
It may be :
outreg, or stat(ci)
Hope this help

Maybe someone has used this version of outreg and has some hints about how to get the output with OR, p-value and conf interval? I also would like to report the value of the constant.

Are you getting an error message, or are you just not getting things printed out that you would like, or what? It would help to show the command you typed before outreg, along with the message or output you got immediately afterwards. I might also drop the "using results" temporarily so the output is printed to your screen.
