<b>MULTIPLE COMPARISON PROCEDURES </b><b>FOR HIGH-DIMENSIONAL DATA AND THEIR ROBUSTNESS </b><b>UNDER NON-NORMALITY </b>

Abstract

This paper analyzes whether procedures for multiple comparison derived in Hyodo et al. (2013) work for an unbalanced case and under non-normality. We focus on pairwise multiple comparisons and comparisons with a control among mean vectors, and show that the asymptotic properties of these procedures remain valid in an unbalanced high-dimensional setting. We also numerically justify that the derived procedures are robust under non-normality, i.e., the coverage probability of these procedures can be controlled with or without the assumption of normality of the data.
