WebI am forecasting a financial variable using auto.arima in R. The result was an ARIMA (1 1 0) (0 1 0) 12. So I only have 1 coefficient with value -0.4605. Without the seasonal effect I know the equation would be Yt = Yt-1 - 0.4605 * (Yt-1 - Yt-2) So the value today is equal to the last value - beta times the lag delta.
