"WebAlgorithms forecast computes the forecasted response MSEs, YMSE, by treating the predictor data matrices ( X0 and XF) as nonstochastic and statistically independent of the model innovations. Therefore, YMSE reflects the variance associated with the unconditional disturbances of the ARIMA error model alone. forecast uses Y0 and X0 to infer U0. " - Forecast algorithm matlab
