Hi Roy,
Thank you for your response.
Actually,for your point 1 (I am sorry if I was not clear) I just used
the command: mfx compute and I got the message "warning: predict()
expression  unsuitable for standard-error calculation
>option nose imposed

>Marginal effects after biprobit
>       y  = Pr(vart,varotc=1) (predict)
>          =  .05270474

and then I got the table with the estimates of marginal effects dy/dx
without the standard errors.

so my question is what is this y=.05270474 that comes before the table?
Thank you,
nirina

Nirina wants to know about biprobit, mfx, and outreg2.

1. It is almost impossible to diagnose your biprobit results without knowing
exactly what you did. Did you use this option, that option.... a verbatim
posting of the command is usually required and more likely to get a useful
answer.

2. To report mfx, you should use Richard Williams' -mfx2-, which stores the
marginal effects in e(b) and e(V) matrices.

ssc install outreg2, replace
ssc install mfx2, replace
sysuse auto, clear
gen alien=foreign
replace alien=1 in 1/3
biprobit (alien mpg rep78) (foreign mpg rep78)
outreg2 using c:\that_was_easy
mfx2, replace
outreg2 using c:\that_was_easy, see

outreg2 needs about 20 more lines to this internally.
