Dear Experts,

1. If there is heterogeneity in the panel model/data, is it true that the appropriate model is either the Fixed Effect or Random Effects model? 

2. I want to choose the appropriate panel regression model when there are autocorrelations, heterogeneity, multicollinearity, and non-normality. Any guiding non-highly mathematical materials that you can suggest?

Thank you.

Hi, these questions are generic and not gretl-specific and as such this list is not the best place to ask them. Others have suggested some textbooks, as the questions are also quite fundamental.

cheers
