本文利用Weibull分布可靠度的置信限得到极大值Ⅰ型分布的变异系数■的置信限。
Suppose r. v. X is distributed as the largest extreme value distribution type I with density function 1/σ exp {-(x-μ/σ)}exp {-exp[-(x-μ)/σ]}, σ>0. The coeffcient of variation of X is δ=πσ/6^(1/2)(μ+σr) where r is the Euler's constant. Let X_1, X_2,…, X_n be an iid. sample from X. In this paper, the confidence limits for δ was obtained via the confidence limits for reliability funotion of Weibull distribution.
