Re: st: AW: Suest v/s biprob in stata 11

[Prakash Kashwan <pkashwan@umail.iu.edu>]

Hi Martin,

Thanks so much for a prompt response. By user friendly menus, I meant
the SPSS kind of interface that Stata 11 has to offer. In the process
of responding to your query I have also discovered that Stata 11 does
offer a similar menu for the suest command, but still doesn't give me
test statistics. Below, I describe the two different ways in which
Stata 11 carries out 'Seemingly Unrelated Estimation'

Menu -1:  Statistics > Statistics > Binary Outcomes > Seemingly
unrelated estimation

This menu runs the following command

 biprobit (probit model 1) (probit model2), vce(robust) noskip
difficult nonrtolerance


Menu -2: Statistics > Postestimation > Tests > Seemingly unrelated estimation

This one runs the suest command

suest probitModel1 probitModel2, vce(robust)

And, this is the one I want to use, but it doesn't give me test
statistics; basically to find out if suest offers me additional
leverage (as compared to each of the models run independently).


Many thanks,
Prakash
