Simulation

Simulations provide a powerful way to answer questions and explore properties of statistical

estimators and procedures. In this chapter, we will explore how to simulate data in a variety

of common settings, and apply some of the techniques introduced earlier.

10.1 Generating data

10.1.1 Generate categorical data
