Hi everybody, I have fitted an ar(1),Garch(1,1) model to some observations with the help of the garchFit function which is in the fGarch package. Here what I've done: library("fGarch") fit = garchFit(formula=~ar(1)+~garch(1,1), data=garat) Now I want to count AIC for this model. How can I do it? I cannot do it with the AIC function of stats package, because R tells me: "Error in UseMethod("logLik") : no applicable method for "logLik" Best regards, Vasileios Ismyrlis

...e box to the most extreme data points defined by the values of the IQR times range (default 1.5). It suggests that the upper and lower plot whiskers should be more less the same length. What does it mean if they are not? How it's possible? I'm using default value of the range. Would be garateful for any hint. Kind regards, Barbara [[alternative HTML version deleted]]
