This is a good place to start. As far as confidence intervals go, with the boot.ci() function, I would recommend paying most attention to type=”stud” (for Studentized) and type=”bca” (for Bias-Corrected and Accelerated) results, since these have been shown to be the most accurate in an academic comparison.

Bootstrapping is any test or metric that uses random sampling with replacement (e.g. mimicking the sampling process), and falls under the broader class of resampling methods. Bootstrapping assigns measures of accuracy (bias, variance, confidence intervals , prediction error, etc.) to sample estimates. Bootstrapping in R – A Tutorial Eric B. Putman Department of Ecosystem Science and Management . Bootstrapping •Resampling technique with replacement # R in Action (2nd ed): Chapter 12 # # Resampling statistics and bootstrapping # # requires packages coin, multcomp, vcd, MASS, lmPerm, boot # Bootstrapping is so trivial you can just code it from scratch. Below, I just use t.test() with the defaults; you can choose var.equal=T, alternative="greater", etc., if you'd like. I set the seed, so your results would be identical, if you don't do anything different.

This procedure is known to have certain good properties and the result is a U-statistic. The sample mean and sample variance are of this form, for r = 1 and r = 2. See also 2008-02-07 · Bootstrapping in Stata . Stata's bootstrap command makes it easy to bootstrap just about any statistic you can calculate. The results of almost all Stata commands can be bootstrapped immediately, and it's relatively straightforward to put any other results you've calculated in a form that can be bootstrapped.
