WebBootstrap and permutation tests can be used to compare means (or other statistics) between pairs of samples. The general idea is simple, and it can be implemented in more ways than I can count. Here, I use existing tools and the fact that a comparison of means can be construed as a test of a linear model. We will be able to use similar code ... Webn_resamplesint, default: 9999.
