Hi all,

I am using -suest- to compare coefficients of the same variable across two logit model (using -test-). My models include nine year-dummies and many other variables. The first model is named "All_es" while the second one is named "All_ls". I tried to run suest but I got the following message:



Code:
suest All_es All_ls
which gives me the following error;


too many base levels specified
r(198);
Without these year dummies, I won't get this message. But, I need these dummies for correct specifications of my two models (i.e., "All_es" and "All_ls).

Any solution? I am using -suest- to be able to use -test- command afterward. -test- runs a chi-squared test to compare coefficients. How can I do this manually (my models have the same number of variables. They are run on two different sub-samples)?


Thanks,
Navid
