Partial concurrent adjustment → Estimate regression coefficients + Arima model

The Partial concurrent adjustment → Estimate regression coefficients + Arima model option means that the ARIMA model, outliers and regression variables (except the calendar variables) are re-identified. All parameters are re-estimated. The transformation type remains unchanged.

The picture below presents the initial model (on the left) and the results of the refreshment procedure with the Partial concurrent adjustment → Estimate regression coefficients + Arima model option (on the right). The ARIMA part has been re-identified (a change from (2,1,0)(0,1,1) to (0,1,1)(1,1,1)). Also the regression coefficients for the calendar variables have been re-estimated. In the revised model there is no Prespecified outliers section. Therefore, the outliers were re-identified.
