WebApr 22, 2024 · “Just bootstrap it” means to treat the data as a population and draw samples from your data WITH REPLACEMENT. The gist of bootstrap is that, if you can’t draw more samples from the original population, drawing samples from the empirical distribution is the next-best option. – Dave Apr 22, 2024 at 16:51 4 WebThe fourth approach to generating sample values of random variables consists simply of approximating in some way a probability distribution by another distribution which is simpler to simulate through one of the three earlier methods.
