Hello, I have problems with garchFit. When trying to fit a time series, I got the following error :
> garchFit(~garch(1,1),data=x,trace=F) Error in solve.default(fit$hessian) : Lapack routine dgesv: system is exactly singular The method works fine on series generating by garchSim. What could be the problem with the time series I use ? Thanks, Sylvain ************************************************************************* This message and any attachments (the "message") are con...{{dropped:13}} ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
