Define Group
The Define button group includes all of the functions for building a full model, including the tools to define inputs using both @RISK functions representing standard probability distributions, tools to fit a distribution to existing data, and create time series and correlations.
Distribution
Add or edit probability distributions in the formula for the currently selected cell.
Output
Add the currently selected cell or range of cells as a simulation output.
Fit
Fits a distribution to a set of data.
Time Series
Add or edit a time series model.
Correlation
Defines correlations (or copulas) for probability distributions or related input variables.
Function
Inserts an @RISK function in the selected cell.
Model
Displays a list of the current output cells along with all distribution functions entered in the worksheet.
