[R] Having trouble getting GARCH parameters (basic/newbie)

2007-12-09 Thread caffeine
I'm having no luck getting GARCH parameter estimations. It seems simple enough, but I don't know what I'm doing. I'm a newbie both at R and GARCH models, so whatever is going wrong, it's probably very basic. Here's what I do: 1. I first load the tseries package with: library(tseries) 2.

You are probably using Windows: you didn't say. If so, this is a known bug in the tseries package: it uses Fortran I/O and that fails in Rgui. The fix (until the package is updated) is to use Rterm instead. On Sun, 9 Dec 2007, caffeine wrote: I'm having no luck getting GARCH parameter
