Design Simulation

To display the Design simulation dialog box:

  1. Select Design Simulation on the

    Distributions & Simulation Analysis

    Startup Panel -

    Quick

    tab
  2. Click the OK button
  3. Use the options in this dialog box to specify for each variable in the matrix spreadsheet a specific distribution from which to simulate random data. In addition, there are options to save the selected specific distribution names and parameter values back into the input matrix spreadsheet.

Variables

The variables in the matrix spreadsheet are listed in this box.

Predefined distributions

Select one variable from the Variables list box and click this button to display the Default distributions dialog box, where the parameters of the selected distribution can be customized.

Select all

Click this button to select all the variables in the Variables list box.

Set defaults for selected variables

Click this button to specify the selected distribution for each selected variable in the Variables list box as the default distribution specified in the matrix spreadsheet.

Distributions

From this list, select the desired distribution to customize.

Parameters

Click this button to display the Define distributions dialog box, which is used to specify parameters for the selected distribution.

Custom parameterized distributions

After selecting a distribution and specifying the parameters, the parameterized distribution will be displayed in this list box.

Apply

Click this button to specify the selected distribution in the Custom parameterized distributions list to the selected variables in the Variables list.

Delete

 Click this button to delete the selected Custom parameterized distribution(s).

Clear all

Click this button to delete all Custom parameterized distributions.

Selected distributions

All variables and their specified distribution are displayed in this list.

Delete

Click this button to delete the highlighted Selected distribution(s).

Matrix

Click this button to produce a matrix spreadsheet of the current correlations and specified distributions for each variable.

Save to input

Click this button to save the current distribution information for each selected variable to the input Matrix spreadsheet.

OK

Click this button to display the Simulation Methods dialog box, where you can simulate random data from the specified custom distributions.

 Simulated data can be generated independently for each column, or you can select to preserve the correlation structure between the variables.

Cancel

Click this button to close the Design simulation dialog box.
