I have two sets of data that are not time series. I would like to fit 
separate linear models (intercept and slope) to each set of data and 
then test if the models are the same (intercepts and slopes are equal). 
I understand that this may be done with the Chow test and that Gretl 
offers this test. Can I do what I want here with the Chow test in Gretl? 
Thanks.
Tom
