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 On 7/22/07, roy wada <roywada@hotmail.com> wrote:

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.
