I am using the forecast package in R to do ARIMA forecasting with auto.arima () function by Professor … Web7 ott 2015 · ARIMA (0,1,1) is a random walk with an MA (1) term on top. The forecast for a random walk is its last observed value, regardless of the forecast horizon. The forecast for an MA (1) process is nonzero only for horizon h = 1. Thus you get a constant forecast (equal to the last observed value plus one value of MA (1) term) beyond h = 1.
