I have around 4000 observations of a time series. I am trying to fit a regression with ARMA error structure using gls from the package nlme. I have encountered the error: cannot allocate vector of size 126064 Kb I know this has come up many times before and I will check out the suggestions in the mail archive. I was wondering though if there is an alternative package that will fit such a model? I did a quick help.search on ARIMA and ARMA but only found arma and arma0.
Both will `fit a regression with ARMA error structure', recursively rather then via computing a large matrix.
