Dear Statalisters,

I am trying to run a two-stage Heckman model with a linear probability model in the first stage instead of a probit. The goal is to apply the Olsen (1980) method. My problem is that I cannot figure out how to construct the control for selection bias once I have run the linear probability model. Has anyone tried to do this version of the Heckman model before? I would be very grateful for any suggestions.

Kind regards,
