Dear Ananya:
After you estimate each model type -estimate store modelname-, whereby modelname is a different
name you give to each model result. After you have estimated all your models type -estimates table
model1 model2, stats(aic bic)-
Hope this helps,
Maarten

I am trying to compare different discounting models and have written ml programs to estimate
parameters for the exponential and the hyperbolic discounting functions using my dataset. I would
now like to be able to compare these two models. Given that they are non-nested, I am having
difficulty finding appropriate tests. I would like to be able to compare AIC and BIC for these
models but when I try using fitstat it doesn't work. Can anyone suggest another way of doing it,
other than calculating AIC by hand?
