Reverse Regression, Fairness, and Employment Discrimination
通过比较正向回归与反向回归两种方法，探讨如何利用统计调整来研究薪酬歧视，并指出公平性包含薪酬比较和资质比较两个维度，为评估就业歧视提供分析框架。
Possible salary discrimination can be studied by comparing mean salaries of, say, males and females, after statistical adjustment for differences in job qualifications. The adjustment is often made by regression, with salary as dependent variable, and job qualifications and sex as independent variables. One might also regress job qualifications on salary and sex, a procedure called reverse regression. Ideas about fairness as well as technical concepts are relevant to discrimination studies. There are two distinct aspects of fairness, one based on comparisons of salary and the other based on comparisons of qualifications. Both concepts are needed to evaluate fairness.
