Dear All, Sorry to bother. I'd like to estimate GARCH-M( GARCH IN THE MEAN) model. And find that a package called rgarch could help. But I always can't instal rgarch package successfully. I posted my problems and got some suggestions but still failed. Does any one knows other method that could do GARCH-M model? I appreciate your time and help!
