Setting Capability Calculation Options

After you activate the process capability features, you can set a variety of options to further customize these features for the situation.

  To set the process capability options:

  1. Display the Statistics tab of the Run Preferences dialog.

  2. Click Options.

    The Capability Options panel opens.

  3. Indicate whether metrics should use short-term or long-term formulas, depending on the time-span of the model.

    You can specify a value from 0 to 100.

    The default is 1.5. If don’t want to use a Z-score shift value, enter 0 in the box or delete the current value and leave it empty.

  5. Indicate whether metrics should be calculated from a fitted distribution or directly from the forecast values (Calculation Method).

  6. When settings are complete, click OK.
