st: booststraping in two stage models

["Danny Cohen-Zada" <danoran@bgu.ac.il>]

I have a question that is relevant to all two stage models. For example, 
take the ivprobit model. If for any reason i want to obtian bootstraped 
standard errors. Can i do the following procedure.

1) estimate the first stage.
2) use predict, pp
3) estimate the second stage by probit (in which we substiture pp instead of 
the endogenous regressor) using the vce(boot) option.

Will this be correct or should i bootstrapct the two stages together. If i 
must bootstrapt the two stages together, how should i do it?

thanks,

Danny
