Simulate

Answer Challenging Questions with Parametric Resampling

The Simulate feature provides powerful parametric and nonparametric simulation capability. Use Simulate to do the following:

• Expand on the bootstrap to provide parametric bootstrapping.

• Obtain power calculations in nonstandard situations.

• Approximate the distribution of statistics, such as predicted values, and confidence intervals, in nonstandard situations.

• Conduct permutation tests.

• Explore the effect of assumptions about predictors on models.

• Explore various “what if” scenarios relative to your models.

• Evaluate new or existing statistical methods.

The Simulate feature is available in many reports, including all of those that support Bootstrap. To access Simulate, right-click in a report.
