Reverse Regression, Collinearity, and Employment Discrimination
指出就业歧视数据分析中直接回归与反向回归看似矛盾的结果，实际上是数据共线性的表现，并给出一个易于实施的准则来提醒分析者注意共线性污染，并用第七编诉讼中的就业数据加以说明。
Apparently contradictory results between direct and reverse regression in employment-discrimination data analysis are a manifestation of collinearity in the data. An easily implemented guideline that alerts the analyst to the presence of contaminating collinearity is illustrated with employment data from Title VII litigation.
