无失效数据的Logistic分布参数的加权最小二乘估计

Weighted least squares estimation of logistic distribution parameters of no failure data

本文给出在无失效数据情况下,当产品寿命服从Logistic分布时,产品寿命的失效率=(<)i ip P t t的参数的加权最小二乘估计以及产品可靠度的估计。

In the case of no failure data, when the product life is subject to logistic distribution, this paper analyzes weighted least squares estimation of parameters of = (<)iip Ptt, the failure rate of product life, and product reliability estimation.
