Approximate Confidence Limits on the Mean of X + Y Where X and Y Are Two Tabled Independent Random Variables
两个有统计表的独立随机变量之和的均值近似置信限
A general method is developed for obtaining confidence limits on the mean of X + Y where X and Y are two independent random variables whose individual distributions and percentiles are in standard statistical tables. The procedure uses this information to obtain approximations for the percentiles of the sum or approximate confidence limits on the mean of the sum. The method is applied to two problems: approximating the percentiles of the noncentral t distribution, and…
