Note on Sawilowsky's paper on the rank transform.
It is shown that the undesirable properties of the rank transform in two-way anaylsis of variance with an interaction are due to the test construction and not to the sampling distribution used. It is furthermore confirmed that a safe procedure is to test for main effects only if the interaction is shown not to be significant.
