Changing the Distribution View and Interpreting Statistics

The forecast settings related to distribution type determine the overall appearance of a forecast chart. You can also choose to display a table of statistics or percentiles instead of or in addition to a chart.

  To set the distribution type or display a data table:

  1. Open the View menu in the forecast window.

  2. Select a distribution type or other view to display on the forecast chart:

    • Frequency — Shows the number or frequency of values occurring in a given interval. This is the default distribution type.

    • Cumulative Frequency — Shows the number or proportion (percentage) of values less than or equal to a given amount.

    • Reverse Cumulative Frequency — Shows the number or proportion (percentage) of values greater than or equal to a given amount.

    • Statistics — Shows a full set of descriptive statistics for a simulation in the forecast window.

    • Percentiles — Shows percentile information in 10% increments, where a percentile is the percent chance, or probability, of a forecast value being less than or equal to the value that corresponds to the percentile (by default).

    • Goodness Of Fit — If distribution fitting is selected in the Forecast or Preferences, then Forecast menus, shows goodness-of-fit statistics for the selected distributions and ranking methods.

    • Capability Metrics — If process capability metrics are set for display, shows a table of process capability (quality) statistics for the simulation (Viewing Capability Metrics).

    • Split View — Shows all selected views simultaneously (Using Split View).
