Good day everyone,
 
I fitted a garch model using garchFit from the fGarch package, and I would like to extract the log-likelihood of the fitted model or its corresponding AIC and BIC values.
 
When I use the summary function, I see that it provides me with the values mentioned above. However, I want to extract them into a matrix of a data.frame. I used the logLik function I receive the following error:
 
Error in UseMethod("logLik") : no applicable method for "logLik"
 
The steps that I followed are as follows:
 
fit = garchFit(~arma(3,3)+garch(1,1), data)
S = summary(fit)
logLik(S)   -   or logLike(summary(fit))
 
Do any one know how to extract these values from a summary function or the garchFit function.
 
Any help will be appreciated,
 
Mohammad
