Comments on ScottKnottESD in response to "An empirical comparison of model validation techniques for defect prediction models"

In this article, we discuss the ScottKnottESD test, which was proposed in a recent paper "An Empirical Comparison of Model Validation Techniques for Defect Prediction Models" that was published in this journal. We discuss the implications and the empirical impact of the proposed normality correction of ScottKnottESD and come to the conclusion that this correction does not necessarily lead to the fulfillment of the assumptions of the original Scott-Knott test and may cause problems with the statistical analysis.
