Hi college,
I am learning econometrics on my own (as it is not my major in university), but hope to work with these data in the future. payment card data could be treat by tobit model. When I concern about economic issue, I could use corner solution tobit model to treat with the data. But then I find it hard to interpret data or at least find the equation - to find out the E(y[y>0), I read book but I do not understand and do not know how could deal with the data after run tobit with ll().
Could some one give me suggestions?
Thank you in advance!
