The “New” Statistics: Resampling and Bootstrapping

In Chapter 17 you learned how you can do simulations of various statistical processes in R by generating random data. In Chapter 18, we turn the tables and work only with sample data. We will still be simulating, however, because we will use resampling and bootstrapping to generate multiple samples with replacement from our original data. In essence these are nonparametric techniques, because we are not making assumptions about populations when we analyze the sample data.

The techniques presented in this chapter have actually been around (at least conceptually) for a very long time. ...
