HI
I am currently investigating the link between a particular stock y and the market index, S&P 500.
I am trying to apply the ARCH model but I end up with the following message. "flat log likelihood encountered, cannot find uphill direction". I really dont know what to do. Any advice would be
greatly appreciated.
what ive done:
reg dly dlsap
estat archlm, lags(1)
arch dly dlsap, arch(1) garch(1)
Kind regards,
Yannick
