Remove Autocorrelation and heteroskedasticity of a time series regression model
Hi,
I have some problems of autocorrelation (serial correlation) and heteroskedasticity in a regression model but I don't know how to remove it. I read on the net that we have to use the Newey-West estimator but I don't know how the way to use it on Shazam.
Thanks a lot,
Brice
