摘要
通过利用分布函数的凹凸性质合理地构造了无失效数据(t1,n1)在t1时刻的失效概率p1=P{T<t1}的一类先验分布,利用贝叶斯定理给出了无失效数据失效概率的一种估计.最后,结合实际问题进行了计算.
A form of prior distribution about the fail-probability Pi, in time t1 of zero-failure date (t1, n1) is developed reasonably by using the convex and concave property of distribution functions. Basing on the prior distribution, we obtain the Bayesain estimations about P1, in time t1. Finally, Calculation is performed regarding to practical problem.
