Concerns on Monotonic Imbalance Bounding Matching Methods

TL;DR

This paper critically examines the Monotonic Imbalance Bounding (MIB) matching method, highlighting its conceptual inconsistencies, lack of generalization, and absence of statistical insights compared to existing methods like EPBR.

Contribution

The paper provides a critical analysis of MIB matching, questioning its theoretical foundations and practical advantages over established matching techniques.

Findings

Identifies inconsistencies in the MIB property definition

Shows MIB does not generalize EPBR property

Highlights lack of statistical information in MIB matching

Abstract

Concerns are expressed for the Monotonic Imbalance Bounding (MIB) property (Iacus et al. 2011) and for MIB matching because i) the definition of the MIB property leads to inconsistencies and the nature of the imbalance measure is not clearly defined, ii) MIB property does not generalize Equal Percent Bias Reducing (EPBR) property, iii) MIB matching does not provide statistical information available with EPBR matching.
