Hello everybody! I'm having this problem with the auto.arima function that i've not been able to solve. I use this function on time series that contains NA values, but every time that the resulting model contains drift I can't perform a forecasting (using forecast.Arima function). The printed error (when I try to forecast the resulting model) claims a dimension mismatch "nreg=newxreg" Here is what I've been triyng to do>ser<-auto.arima(x,start.p=0,start.q=0,start.P=0,start.Q=0,trace=TRUE,stepwise=TRUE); >forecast(ser,h=12)x is ts object (-monthly data-) Thanks [[alternative HTML version deleted]]
hello, i have a doubt with this function, i need get the returns values because i have to save in a variables,something like this: Invernadero<-ts(x2) test<-auto.arima(x2) x2.pred.ar31<-predict(arima(x2,order=c(p,d,q)),n.ahead=10)$pred can i get "p","d" and "q" from "auto.arima"?this is my question. I hope have explained well, A regards. -- This message was sent on behalf of yonosoyelmejor at hotmail.com at openSubscriber.com http://www.opensubscriber.com/message/r-help at r-project.org/11277758.html
