Hi R,
Was just checking the "?ar ", the autoregressive model. It's great that R can give the order of the autoregressive model. Suppose if I had 2000 observations to fit an AR model. Then, if I am correct R builds 33+1 autoregressive models (10*log10(2000)=33) and select the order at which the aic's of the models were the least. My question is whether the procedure "?arima " can throw the orders (p and q) of the arima model?
