Sorry to keep quizzing the r-helpers but I'm having real difficulty with arima.
I am happy that i have chosen the best fitting arima model for my data,(in this case arima(1,1,1) but when i use the predict function the forecast damps to a constant value after just two or three values, and from a time series of almost 3000 values i am left with only a couple of predicted values. I have tried aggregating my data to condense finely spaced time points into larger clumps but to no avail. please can someone offer a little advise on how i might improve on this? thank you, Laura Quinn Institute of Atmospheric Science School of the Environment University of Leeds Leeds LS2 9JT tel: +44 113 343 1596 fax: +44 113 343 6716 mail: [EMAIL PROTECTED] ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
