Hi. I hope you can help me... I have fitted the following ARIMA model: arima1<-arima(bigspring$log.volume, order=c(0,1,2)) I need to predict 30 days ahead. I used following code predict(arima1,n.ahead=30,se=T) However I get 30 predictions, but from predictions 2:30 I get the same predictions. Why is this? What am I doing wrong Thanks Catherine KSS Ltd Seventh Floor St Jam...
