Separating regression into males and females

[Nthato Ras]

Hi All,

I have a logit regression and would like to have results for males and females separately.

 logit weight i.finc i.feedingscheme i.gender i.race i.geotype

I don't want to show gender as a control variable, but to have separate regression results for males and females.

Please advise.

Regards
Nthato

you appear to have 2 choices: (1) eliminate i.gender from your command and add something like "if gender==1" (since you did not provide a data example (use -dataex- please; see the FAQ), I have to guess; then estimate a second regression using "if gender==0" (with same caveat); (2) if you are interested in seeing how one or more of your other variables varies by gender, you can use an interaction of that (those) variable(s) with gender; see

help fvvarlist

for how to do that

Hi Rich,

Thanks for the response. I am interested in seeing how all my variables vary by gender.

My data is as follows:

Hi Rich,

I used the 1st option to look at males and females separately, and it worked perfectly.

Thanks
