I need to conduct Heckman style self-selection bias test.
For the first stage of this test, the selection probit model, I have a
number of alternative DVs, all of whom are continuous variables. Can I
dichotomize a continuous variable, so that it can be used as a DV in the
probit model?

Will appreciate very much any advice on this.
