Dear all,


I have taught myself panel data, so I am not really sure what I am doing.

I am estimating a fixed period and fixed time effects unbalanced panel model and i have detected heteroskedasticity, but I also think I have some form of correlation as my DW statistic was quite low, but critical values are not availiable so I can't be sure.

For ease, I was wondering if there is any way, shape or form that I can calculate Newey-West robust errors to take account for both effects in panel data? I saw that it was listed under time-series options, but then I will have to declare my data as time series rather than panel and I don't know what effect that would have.

I think that if I change my method or estimator now, I will just end up confusing myself more and applying this sorts out both of my problems.

If STATA don't have a method, is there any laymans way of explaining how I can calculate these standard errors by hand?
I am not very comfortable using white standard errors know I know about how they are wrong if correlation is present

Many thanks,
