Copula Command Buttons

The Command Buttons for the Define Copula window includes:

  • Help - Open help resources (online or local, based on @RISK settings); see Help Button for more information.
  • Edit Copula - Add, remove, or edit inputs; also includes commands for working with instances. See Edit Correlation Matrix for more information.
    • Append - Add inputs or rows to a correlation matrix.
    • Remove - Remove inputs or rows from a correlation matrix.
    • Replace Input - If the selected row or rows in the matrix are inputs, remove the currently selected input(s) and replace them with different inputs.
    • Fill In Slot - If the selected row or rows in the matrix are missing inputs, opens a dialog to select inputs for those rows.
    • Reorder Rows - Opens the Reorder Inputs dialog to modify the order of rows in the matrix.
    • Instances - Create, modify, or remove instances of a correlation matrix. See Correlation Instance Editor.
  • Settings/Actions - Window-specific settings and actions. The Define Copula options are:
    • Delete Matrix/Copula - Removes the correlation matrix or copula from the @RISK model entirely.

    • Please note: Deleting a copula will remove the copula data from the worksheet, and this action cannot be undone!

      This will not remove the inputs that are a part of the correlation or copula! However, it will remove the RiskCopula property function from any inputs that have been connected to the copula.

    • Check Matrix Consistency (Gaussian and t Copulas Only) - Check the consistency of the correlation coefficients. If @RISK detects that the correlation coefficients are invalid, it will prompt for permission to correct the coefficient values to the closest valid matrix values. See Correlation Matrix Consistency for more information.
  • Correlation Coefficients (Gaussian and t Copulas Only) - View and edit the correlation coefficients. See Define Correlation Matrix.
  • Graphs - View the correlation or copula matrix with the graphs of the input distributions and scatter plots of correlated inputs. For correlations, coefficients can be edited from this screen. See Correlation and Copula Graphs.
  • Instance Editor - View and the correlation or copula instances. See Instance Editor.
