Setting Run Preferences

  To specify the number of trials and initial seed value (so the charts will look like this tutorial):

1. Select Run Preferences, , in the Crystal Ball ribbon, and then select Trials.

   The Run Preferences Trials dialog opens. For this example, running more trials will help achieve more accurate forecast results.

2. In the Number Of Trials To Run text box, type 5000.

3. Click Sampling.

4. Select Use Same Sequence Of Random Numbers.

5. In the Initial Seed Value text box, type 999.

6. Notice that the Sampling Methods group has two choices: Monte Carlo and Latin Hypercube. Latin Hypercube is less random and produces a smoother, more even results chart. For now, though, select the default — Monte Carlo.

7. Click OK.
