Heckman selection model singular matrix

Postby Lalan_dk » Fri Aug 24, 2018 8:38 pm

Hi there,

I have problem with near singular matrix in heckman estimation. I think I don't have dummy variable trap problem. I don't know what the problem is. Maybe anyone can help me?

I run estimation with following command:

Code: Select all

smpl if ar02b=1 and h_income<>NA
equation milk_exp.heckit(2step) exp_milk  h_income head_age head_educ  elder_n children_n @ buy_milk   head_educ  elder_n children_n free_milk

And here the workfile attached
