Hi, I'm working on a multivariate ARIMA model. I have 2 time series and found for each an ARIMA model I'd like to know how are calculated the residuals of my arima model using residuals() function in R ? Is it as I think predicted values (from ARIMA model) - observed values ?
Is it relevant to use the residuals of my models to realize the cross-correlation between my 2 time series?
