The Precision tab of the Forecast Preferences dialog manages the precision control settings that determine when to stop a simulation based on confidence intervals for selected statistics.
The current simulation must be reset before precision control settings will take effect.
Select from the following settings:
Specify The Desired Precision For Forecast Statistics — Activates the precision control settings for the forecast. Crystal Ball uses these settings only if the simulation is set to stop when it reaches the specified precision from the Run Preferences dialog (Setting Run Preferences). The statistics available for precision control are the mean, the standard deviation, and an indicated percentile. Select any or all. If you select Percentile, you can enter any percentile value greater than 0 and less than 100 to use as a precision control statistic.
Must Be Within Plus Or Minus — Selects which range to use for precision control, absolute units or relative percentage.
Click OK to apply settings on the current tab to the active forecast. Or, you can click Apply To to apply settings on the active tab to the active worksheet, the active workbook, or all workbooks. At any time, you can click Defaults to restore the original default settings on the active tab in the dialog.
