Bootstrapping vs permutation

WebWith 1000 permutations the smallest possible p-value is 0.001, and the uncertainty near p = 0:05 is about 1% If we have multiple testing we may needmuchmore precision. Using 100,000 permutations reduces the uncertainty near p = 0:05 to 0:1% and allows p-values as small as 0.00001. A useful strategy is to start with 1000 permutations and continue WebJul 27, 2024 · Permutations vs SHAP vs Gain.

WebNov 23, 2024 · Going to the issue of bootstrap vs. permutation approaches: Note that while they both simulate the sampling distribution, they do so under somewhat different assumptions, i.e., one in which the null hypothesis is enforced (-permute-) vs. one simulated under a particular alternative hypothesis.
