Hi I have data for voting behaviour on two (related) binary votes. I want to examine the second vote, running separate regressions for groups who voted different ways on the first vote. As the votes are not independent, I guess that there is an issue with selection bias.
So, I think I would like to fit a heckit style model but with a binary dependent variable - so, in effect, two successive probits. Is there a way to do it in R? (Alternatively: am I thinking about this the right way?)
