Chapter 12. Resampling statistics and bootstrapping


This chapter covers
  • Understanding the logic of permutation tests
  • Applying permutation tests to linear models
  • Using bootstrapping to obtain confidence intervals


In chapters 7, 8, and 9, we reviewed statistical methods that test hypotheses and estimate confidence intervals for population parameters by assuming that the observed data is sampled from a normal distribution or some other well-known theoretical distribution. But there will be many cases in which this assumption is unwarranted. Statistical approaches based on randomization and resampling can be used in cases where the data is sampled from unknown or mixed distributions, where sample sizes are small, where outliers are a problem, ...
