Dear Statalist members,
I want to use a double hurdle model (Churdle) for my analysis and compare if it fits better than the Tobit model.
The literature have used sometimes used LR test for nested models to compare the two. When I tried using LR test, I get the following error:
. lrtest dhmodel1 tobit1
test involves different estimators: churdle vs. tobit
r(498);
I have same variables in both the models, how can i compare these two on which model fits my data well?
Any help and suggestions are welcome.
