Ordinal Bivariate Inequality: Concepts and Application to Child Deprivation inMozambique
提出一种基于序数双变量分类数据的不平等比较方法，通过相关性增加和中位数保持变换定义不平等关系，并以莫桑比克儿童贫困为例展示应用。
This paper introduces a concept of inequality comparisons with ordinal bivariate categorical data. In our model, one population is more unequal than another when they have common arithmetic median outcomes and the first can be obtained from the second by correlation‐increasing switches and/or median‐preserving spreads. For the canonical 2 × 2 case (with two binary indicators), we derive a simple operational procedure for checking ordinal inequality relations in practice. As an illustration, we apply the model to childhood deprivation in M ozambique.
