威布尔模型的参数估计方法——极大似然法

Failure Models Involving Weibull Modelling and Maximum Likelihood Estimate

利用概率论中极大似然法的理论来探讨威布尔模型的参数估计问题 ,并利用MATLAB的相关命令、函数对它们进行了部分编程 ,主要讨论了三参数威布尔模型的极大似然函数、参数估计和MATLAB程序 .

The paper discusses the parameter estimate of Weibull modelling by using theory of maximun likelihood estimate in advanced mathematical statistics and MATLAB program design language.Importance is attached to maximum likelihood function,survival parameter estimate and a part of MATLAB programs.
