st: Diagnostic tests after -xtreg, fe-
I am estimating a simple fixed-effects panel data model in Stata 9, and I am trying to carry out the usual diagnostic tests afterwards. My regression is
xi: xtreg growth initial i.year, fe robust cluster(regionid)
I've learned about tests for serial correlation and heteroskedasticity. However, I have not found commands for Ramsey's Reset test for omitted variables (an analogue for -ovtest- after -regress-) and the information matrix test that provides a test of skewness and kurtosis (an analogue for -imtest- after -regress-).
Also, is there a way to obtain plots of residuals versus fitted values, leverage versus residuals squared and added variable plots - i.e. all the usual diagnostic plots that are available after -regress-?
Many thanks for your help, it would be much appreciated.
