Re: Autocorrelation and heteroskedasticity in Panel Data

Thanks for your answer,

I have workfile mentioned below. Durbin-watson stat is near zero. That means there is Heteroscedastisity here. What can I do to handle Heteroscedastisity? is it enough to Choos "white cross- section" in "Coef covariance method " ?

Thank you so much

Re: Heteroskedasticity and Autocorrelation test for Panel Data

Unfortunatly There is no Heteroscedasticity test in View->Residual Diagnostics->Heteroskedasticity test in my Panel Data. it is only available in undated Data . and Arrelano Bond serial Korrelation test is only available for GMM equations estimated by first differentes. Is there any other way? Thanks

Re: Dummy Variables

that means I should use each variable separately in model and without constant?
for example:
log(export) log(gdb) log(pop) log(distance) @expand(Embargo)
is it correct?
