As far as I know it is possible to compute P(Y1=1|Y2=1) for a bivariate Probit model using the standard Stata commands as mfx, predict(pcond1) .However I would like to compute the P(Y1=1|Y2=0). Is it possible to compute this marginal effects by just creating an alternative dependent variable(Y2c) which takes the complement values of Y2 (ie for Y2=1 then Y2c=0 and for Y2=0 then Y2c=1) and compute P(Y1=1|Y2c=1) instead of P(Y1=1|Y2=0). If yes is it possible to use the same approach for recursive bivariate probit model?? * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
