The bootstrap is a resampling method for statistical inference. It is commonly used to estimate confidence intervals, but it can also be used to estimate bias and variance of an estimator or calibrate hypothesis tests. This article will illustrate bootstrap concepts using a simple example, describe different types of bootstraps and some of their theoretical and practical properties, discuss computation and other details, and indicate extensions that are especially appropriate for environmetric data. The methods will be illustrated using data on heavy metal concentrations in groundwater and magnesium concentration in blood.
