Greetings,
Hello dear professionals, I want to use the endogenous switching regression (ESR) model, however, my treatment is a multivalued treatment effect that takes four ordinal values (i.e. 0, 1, 2, and 3). The commands that I know is compatible if the treatment is binary (treated or not treated), but such the usual commands cannot fit with my research objective. So, Is there any sort of command that can run an ESR model with such multivalued treatment effects?
Thanks,
