Hello, I am in the proceedings of my bachelor thesis and I collected a panel data set of 22 countries over a 25 year period. I would like to calculate the VIF value and do a test for heteroscedasticity but the commands:
- estat vif
- hettest
do not work because of me using a panel data set. I have looked over the web but I can't find a solution that works. How should I proceed?
Kind regards
