Dear Sir/Mad,
I am Uyen,working on my thesis at Groningen University, The Netherland
at present. I am trying to estimate a Heckman two step model that
including two equations.
The first equation is a probit equation which determines whether a
firm offer trade credit or not?
The second equation is a tobit one which specifies how many
percentages of an order by a specific customer of the firm, only in
case the firm giving trade credit to their customers?
I see Heckprob and Heckman where the second equation is a probit or
OLS. Would you please help to give me the do-file of Heckprob that may
help me to make a do file for my own project?
It is even much better, if you may gice me some instructions that i
can run my regressions on stata without any programming?
I am very grateful for your respense.
Uyen
