Hi again,
 
Thank you so much for the quick help although I think I have been slightly misunderstood. I am not looking for the sole probability of being poor in period 2 (y2=1), but the  probability of being poor in period 2 conditional on the poverty status in period 1. The easy solution would of course be to run two estimation e.g.:
 
probit y2 hh if y1=poor
probit y2 hh if y1=non-poor
 
But I am thinking that there would be a correlation between those two, meaning that the poverty status in period 1 (y1) influences the probability of being poor in period 2 (y2), and this would be confirmed with rho different from 0 in a bivariate probit model. Therefore, I am trying to get a table with the following two columns:
 
Probability of being poor in period 2 (for poor hhs in period 1) | Probability of being poor in period 2 (for non-poor hhs in period 1)
 
But how to write that in STATA? As I mentioned previously, I have written:
 
biprobit y1 y2 hh
 
but that does not seem right?
 
Thank you so much for any help,
Kristian
