552: Forecast Settings
The forecast settings option allows you to specify the confidence level used when calculating the prediction intervals for new forecasts. If the confidence level is set at p%, then p% of the prediction intervals should contain the observation. The higher the confidence level, the wider the interval will be. Standard settings are 90%, 95%, and 99%. Note that the new confidence level will only take effect when a new forecast window is opened. The method by which the error variance is calculated can be selected.
