...l ARIMA model from the outputs. To be specifically, which sign to use? I know R uses a different signs from S plus. Is it correct that the model is: (1-ar1*B-ar2*B^2-...)(1-sar1*B^s-sar2*B^2s-....)(1-B)^d(1-B^s)^D X_t=(1+ma1*B+ma2*B^2+...)(1+sma1*B^s+sma2*B^2s+....) a_t For example: > m1=arima(koeps,order=c(0,1,1),seasonal=list(order=c(0,1,1),period=4)) > m1 Call: arima(x = koeps, order = c(0, 1, 1), seasonal = list(order = c(0, 1, 1), period = 4)) Coefficients: ma1 sma1 -0.4096 -0.8203 s.e. 0.0866 0.0743 Should the estimated model be written as: (1-B)(1-B^4) X_t=...
