Measurement of Economic Distance Between Blacks and Whites
提出新的无分布方法估计两组间的经济距离，特别是区间比较，并应用于1967和1979年黑人与白人收入差距分析，涉及分位数投影、平滑经验分布函数、最大熵方法及统计置信区间。
This article proposes new distribution-free methods for estimating the economic distance (advantage) between one group and another, especially for interval-to-interval comparisons, which can be more informative than a single aggregative measure. Novel techniques for computing projected quantiles, smoothing of empirical cumulative distribution functions, maximum entropy methods for finding the upper bound of the richest income interval, and statistical confidence intervals are described and applied to black-white income differences in 1967 and 1979.
