On the Distribution of the Sum of n Sample Values Drawn from A Truncated Normal Population
截断正态总体中样本和的分布
Summary This paper deals with the situation arising when a normal population has all members with values greater (or less) than a given value rejected, and where small samples are drawn from the remaining truncated population. Formal expressions are deduced from which can be calculated the distribution of the sum (or mean) of the sample values as a function of the point at which the original parent population is cut. Tables are given for the integral distribution function of…
