...There are many reasonswhy larger samples aremore appropriate (see Button et al. (2013) for a recent review), and inwhat concerns permutation methods, larger samples allow smaller p-values, improve the variance estimates for each VG (which are embodied in the weighting matrix under restricted exchangeability), and allow finer control over the familywise error rate....
