Confidence Intervals for the Quantiles of a Finite Population: Simple Random and Stratified Simple Random Sampling
有限总体分位数的置信区间:简单随机抽样与分层简单随机抽样
Summary Given a finite population consisting of N units, it is desired to have a confidence interval for the (t/N)th quantile, Y (t), of the population. Assuming simple random sampling, a confidence interval procedure is suggested and several expressions for the associated confidence coefficient are given. With stratified simple random sampling, for L = 2 strata, three confidence interval procedures are suggested. The associated confidence coefficients are derived under each…
