**Hi Vijay:
I had some questions about the Ai codes online:
lrtest(pkfit_1cmp, pkfit_2cmp)
DataFrame([(metric=string(f), fit_1cmp=f(pkfit_1cmp), fit_2cmp=f(pkfit_2cmp)) for f in (aic, bic, ϵshrinkage, ηshrinkage)])
The above code does not work for me for model check. It does not give an error but whole lot of text describing lrtest instead of the results. The dataframe gives out first column BIC and AIC but no results.
Do you have another code for this test?**
