Partial concurrent adjustment → Estimate regression coefficients + Arima parameters

The Partial concurrent adjustment → Estimate regression coefficients + Arima parameters strategy means that the ARIMA model, outliers and other regression parameters are not re-identified. All parameters of the RegARIMA model are re-estimated but the explanatory variables remain the same. 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 coefficient + Arima parameters option (on the right). The parameters of the ARIMA part have been re-estimated and their values have been updated. Also regression coefficients have been re-estimated and the number of estimated coefficients in the revised model is the same as in the initial model (i.e. 16 estimated coefficients). The structure of the model remains unchanged while all coefficients have been updated.
