Abstract
The power divergence family of statistics introduced by Cressie and Read (1984, Journal of the Royal Statistical Society, Series B 46, 440-464) is used to obtain approximate confidence intervals for the ratio of two proportions. Intervals based on inverting the Pearson, likelihood-ratio, and Freeman-Tukey statistics are included in this family. Small-sample comparisons of the intervals are presented.
摘要
Cressie和Read（1984年，《皇家统计学会杂志》，B辑46卷，440 - 464页）引入的统计量的幂散度族用于获得两个比例之比的近似置信区间。基于Pearson统计量、似然比统计量和Freeman - Tukey统计量的区间反转得到的区间也包含在这个族中。文中给出了这些区间的小样本比较。
