I have a data file with a given time series of price data and I would like to split the time series into a test set and training set. I would then like to build an ARIMA model on the training set and apply this model on test set. Below is some code: [CODE] data= read.table("A.txt",sep=",") attach(data) training = data[1:120, 6] test = data[121:245, 6] ts1 = ts(training) ts2 = ts(test) arima1 = arima(ts1) arima2 = arima(ts2) [/CODE] -- View this message in context: http://r.789695.n4.nabble.com/R-time-series-analysis-tp2527513p2527513.html Sent from the R help mailing list archive at Nabble.com.
