John,

Thanks much for the info.  Will try working with outreg (use to use it long time ago). Just tried your code and got an error msg. saying `option keep() not allowed'.  I updated to sg97_3  but still did not work.  will look around and see if I can find the correct update with the keep option. 


Thanks,fb

Farasat,

The fact that the logit and probit results do not merge as you expect in -outreg2- is due to a change in the way Stata reports the results of these estimations in the e(b) matrix.  For some reason, although the models are univariate and there are no auxiliary statistics in e(b), Stata added the independent variables as equation names in version 10.  Since you use different independent variables (at least in name) in the two estimations, -outreg2- thinks the coefficients are different.

In -outreg- (_not_ -outreg2-) which I am more familiar with since I wrote it, you can get around this by lopping off the equation names using the -keep- option:

sysuse auto, clear
clonevar for2 = foreign
logit foreign mpg turn price headr, or robust
outreg, keep(foreign:) or replace

logit for2 mpg turn price, or robust
outreg using a, keep(for2:) or merge

Two differences from your example: 
    - you need the -or- option to get odds ratios in the -outreg- table
    - this saves to a Word document, not an Excel table

In -outreg-, this would have worked without the -keep- option if the independent variables had had the same name in both estimations:

sysuse auto, clear
clonevar for2 = foreign
g i = 1
logit foreign mpg turn price headr if i == 1, or robust
outreg, or replace

logit foreign mpg turn price if i == 1, or robust
outreg using a, or merge

> If this is intentional then I missed it in the help file -- if not, it might be worth emailing the author (Roy Wada) and seeing if he is willing to change this behavior .  If you add the option 'sideway' to the logit -outreg2-, the coefficients line up (but the SE are no longer under the coeff).

I have even tried forcing it by using the "wide" option (which is the default anyway) but the output file does not contain columns next to each other but rather vertically stacked. The prob. has started showing up in my stata 11.2 MP  (was not there in state 10). Any suggestions on how to proceed?
