Correcting for autocorrelation and hetroskedasticity in panel data
Hello everyone
I have an inquiry about correcting for auto-correlation and hetroskedasticity in panel data. Is there a test that can correct for both issues. My population is around 102 * 5 years that is 507 observations N=507 , T=5 (fixed effect & unbalanced data).
I am not sure whether to use both xtregar and xtreg ,fe robust OR there is another single test that can be best used in my case.
Please suggest me if there is a single test and where can I read more about it.
thank you in advance
