WebMay 31, 2024 · I'm trying to run a same permutation test for the null hypothesis of no difference between means with the coin and resample R packages. However, I get quite different p-values, which I was not expecting. Should the two packages provide such different p-values? Am I performing the same test in the two packages? My minimal reprex:
