So your model would be better estimated using set.seed(1) series <- ts(rnorm(100),f=6) fit <- arima(series, order=c(1,1,0), seasonal=list(order=c(1,0,0),period=NA), method="ML") share|improve this answer edited Aug 30 '11 at 6:36 answered Aug 29 '11 Fired because your skills are too far above your coworkers I wish to try out a technique which my supervisor does not want me to, because its not his expertise What
