Ivan: I'm guessing you've got the latest version of fSeries if you downloaded it recently from CRAN. I've noticed the convergence problems too. I changed to algorithm="lbfgsb" and haven't had a problem since. (I'm running Windows XP and R 2.3.1) John -----Original Message----- From: r-help-bounces at stat.math.ethz.ch [mailto:r-help-bounces at stat.math.ethz.ch] On Behalf Of Ivan Kalafatic Sent: Friday, July 14, 2006 10:26 AM To: r-help at stat.math.ethz.ch; r-sig-finance at stat.math.ethz.ch Subject: [R] Help for updating package I have a problem with garchFit fuction in fSeries package. I found the following reply on one of the R list: "GARCH-Modelling is not easy, and indeed for your dataset the default "Sequential Quadratic Programming" solver doesn't converge. I observed this also for some other time series. There is already an updated version on the server, https://svn.r-project.org/Rmetrics/trunk/fSeries/ which uses improved control parameter settings as default values. With this version there exist no convergence problems" How to update my version of fSeries with the provided link? Thank you. ______________________________________________ R-help at stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
