When carrying out probabilistic simulations, you may often run hundreds or thousands of realizations. In order to analyze the results, it is often quite useful to screen out some of the realizations by classifying the realizations into categories. A category is simply defined by a condition relating one or more outputs in the model (e.g., those realizations in which the discount rate was above 3.5%; those realizations in which the profit exceeded $1,000,000; those realizations in which the peak concentration was between 1 mg/l and 10 mg/l).
Classification categories are defined at the bottom of the Monte Carlo Result Display Properties dialog:
This dialog can be accessed from the Monte Carlo tab of the Simulation Settings dialog (via the Result Options… button), and is also accessible by pressing the Options… button available in the Result Properties dialog of an Array Result element.
You can screen a particular category from the results by clearing the Include box at the bottom of the Monte Carlo Result Display Properties dialog:
Only include those realizations in the categories which you have chosen to include can then be displayed in charts and tables.
Note: You can edit the
Include box in Edit Mode, Result Mode Scenario Mode or Run Mode.
In the example above, the Low and High categories have been screened out, so when displaying results, only those realizations that fall into the Medium category would be available in the realizations spin control at the top of the display window:
