The conditional permutation test for independence while controlling for confounders
Journal of the Royal Statistical Society: Series B (Statistical Methodology), Volume 82, Issue 1, Page 175-197, February 2020., 2020 Summary We propose a general new method, the conditional permutation test, for testing the conditional independence of variables X and Y given a potentially high dimensional random vector Z that may contain confounding factors. The test permutes entries of X non‐uniformly, to respect the existing dependence between X and Z and thus to account for the ...
