Stata bootstrapping

Web15.3 - Bootstrapping. Bootstrapping is a method of sample reuse that is much more general than cross-validation [1]. The idea is to use the observed sample to estimate the population distribution. Then samples can be drawn from the estimated population and the sampling distribution of any type of estimator can itself be estimated. Webbootstrap p value in STATA.
