title: A note on controlling the number of false positives.
abstract: Lehmann and Romano (2005, Annals of Statistics33, 1138-1154) discuss a Bonferroni-type procedure that bounds the probability that the number of false positives is larger than a specified number. We note that this procedure will have poor power as compared to a multivariate permutation test type procedure when the experimental design accommodates a permutation test. An example is given involving gene expression microarray data of breast cancer tumors.
