正态总体未来样本标准差或极差的同时预测区间
This article provides procedures for constructing simultaneous prediction intervals to contain the standard deviations or ranges of all of k future samples, given the standard deviation or range of a past sample from the same normal distribution. The procedures, which use mainly existing tabulations, are illustrated by a numerical example.
多个 Student t 变量最大绝对值的分位点表及应用
A table of lOOγ% points of the maximum absolute valuetof the k-variate Student t distribution with v degrees of freedom and common correlation p is given for various values of k, ν, p and γ. The application of these tables to problems dealing with the construction of simultaneous confidence and prediction intervals is briefly described.
正态分布样本预测区间的补充计算因子
A prediction interval on k future observations is an interval which is said to contain the values of all k such observations with a specified probability based on the results of a past sample of n observations from the same population. Such an interval is frequently required in practical applications. This article provides factors for a normal distribution for These factors were obtained using a new computer program whose accuracy was checked by comparison with existing…
正态总体样本双侧预测区间的计算因子
Factors r(k, n; γ) for a normal distribution are given such that one may be 100γ% confident that the two-sided prediction interval will contain all of k future values, where and s are the sample mean and standard deviation from n previous observations. A special case is a prediction interval for a single future observation, which can also be obtained using percentage points of the Student t-distribution. Curves which indicate the extent to which two previously proposed…
