Comments on the paper 'Type I error and test power of different tests for testing interaction effects in factorial experiments' by M. Mendes and S. Yigit (Statistica Neerlandica, 2013, pp. 1-26)

Abstract

We give some comments on the paper by Mendes and Yigit where some misleading statements on rank tests have been given. Also, we give some additional important references on the same topic, which are not cited in this paper. By extending the simulations presented in the Mendes and Yigit paper to larger and unequal sample sizes, we demonstrate that the main conclusions are misleading.
