摘要
在Ⅰ型截尾场合对极值分布的尺度参数α和位置参数μ的近似无偏估计AUE,然后在Ⅰ型截尾场合对威布尔分布的恒定应力加速寿命试验的统计分析进行研究。得到加速方程的系数的AUE和在正常应力下的各种可靠性特征的估计。最后一个数值例子表明,上述方在计算上是简便的,在应用上是可行。
In this paper we give approximate unbiased estimates (AUE) of sacle parameter σ and location parameter μ of extreme value distribution on type I censoring. Next, we study statistical analysis of accelerated constant-stress life test(ACSLT)for Weibull distribution on type I censor- ing and give AUE of the coefficients in acceleration equation and estimates of various reliability characteristics under the usual stress. Finally, a numerical example in given to show that our method is simple in computation and usable in application.
