    eLet X be a random variable with exponential distribution whose density function is(?) where-∞<μ<∞,O<σ<+∞,bothh and σ being unknown.This paper gives a new estimator of σ.(?)_2=(?)where (?)n is the sample size,r is the number of terms retained when censored on the right,and x_((j)) denotes the i-th order statistic,i=1,…,r.In this paper it is shown that for loss function L((?),or) =((?)-1) ~2,the risk of (?)_2 is much smaller than that of the best affine invariant estimation (?)_1=1/r(?); hence an improvement.

    设 X 是具有指数分布的随机变量,其密度函数为p(x)=(?)其中-∞<μ<+∞,0<σ<+∞,μ和σ均未知。本文给出了σ的一个新的估计(?)+(n-r)x_((r))-nx_((1) )]·f(?)(y),此处y=(?),f(?)(y)=(?)n 是子样容量,r 是截尾数,x_((i))表示第 i 个顺序统计量(i=1,2,…,r)。文中证明了(?)关于损失函数 L((?),σ)=(((?)/σ)-1) ~2比最佳仿射同变估计(?)=1/r[(?)x_((i))+(n-r)x_((r))-nx_((1) )]处处有较小的风险,因此是一个改进。

    为了充分利用验前信息,在小子样的场合下进行统计评定工作,文中运用了Bayes 统计决策方法,讨论了两方面的问题。1.再入飞行器的最大飞行距离鉴定的Bayes 决策方法。引入了损失函数及验前信息,将决策中所冒的风险与射击效果结合了起来。2.Bayes 估计。给出了最大飞行距离的Bayes 统计估值。理论及计算结果表明:合理地使用验前信息,将有利于在小子样容量之下进行最大飞行距离的统计推断工作。

    Let X be a random variable with exponential distribution whose function is ?? where -∞<μ<∞, 00 is known, is inadmissible.
