Simulation Methods
Select
Run Simulation on the
Distributions & Simulation Analysis Quick
Variables
Note that this button is available only if the
Simulation Methods dialog is reached through the
Distributions & Simulation Analysis Startup Panel. Click the
Variables button to display a standard variable selection dialog, in which you select the variables for the analysis.
Run Simulation analysis expects the input file to be a correlation matrix, which can be created by clicking the
Save distribution fit button on the
Fit Distribution Results
dialog -Save Fit
tab.Simulation Methods
The
Simulation Methods group box contains the available methods for simulating data.
Monte Carlo
Select the
Monte Carlo option button to generate random data from the best fitting distributions while ignoring the correlations between variables.
Latin Hypercube Sampling (LHS)
Select the
Latin Hypercube Sampling option button to generate random data from the best fitting distributions by the Latin Hypercube method. Similar to the Monte Carlo method, this method also ignores the correlations between variables.
Correlation Based
Select one of the simulation methods in the
Correlation Based group box to generate random data from the best fitting distribution while preserving the rank correlations between variables.
Iman Conover
Select the
Iman Conover option button to generate random data from the best fitting distributions while preserving the rank correlation structure by the Iman Conover method.
LHS with Iman Conover
Select the
LHS with Iman Conover option button to generate random data from the best fitting distributions while preserving the rank correlation structure by the LHS with Iman Conover method.
Options.
Number of samples
Specify the number of random samples to generate.
Seed random number
Select the
Seed random number check box and specify a constant value to seed the random number generator.
Truncate simulated values to .5% - 99.5% interval.
5% interval. Select this check box to specify that simulated values will fall between the 0.5th and 99.5th percentiles of the theoretical distribution(s).
Auto update on the current spreadsheet
Select the
Auto update on the current spreadsheet check box to generate random numbers into the same spreadsheet for multiple simulation runs.
Simulate
Click the
Simulate button to simulate random data according the specifications set in the
Simulation Methods dialog.
Cancel
Click the
Cancel button to close the dialog without performing an analysis.
