27: Resampling (two-sample tests)

Resampling methods for comparing two samples. Randomization/permutation, bootstrapping, parametric bootstrapping, model-based Monte Carlo analysis.

The difference between randomization and bootstrapping at 7:55 is really helpful

outstanding explanation! really clears things up for me. Nice to see the methods compared and contrasted all in one short video. The graphics help immensely. Thanks!

Thanks a lot, it is incredibly clear and to-the-point.

I know the non-parametric bootstrap doesn't assume normal distribution of the data, but does it assume equal variances between the two samples?

Where does the observed difference at ~6:00 come from?

Should an alternative hypothesis be two-sided?
