There may be some confusion regarding the way you describe the models. When you refer to the first model as the "truncated model" it isn't clear if you're talking about a truncated distribution or if you are just describing a simplified version of your final model. What results are you attempting to compare between the models?

Model 1 is the truncated model and Model 2 is the full model (with additional controls). My questions are: i) what is the methodologically appropriate way of comparing the results from Model 1 with those from Model 2? ii) What command could I use in Stata to get at this comparison?
