Weibull Parameter estimation using Apache Commons Math

I need to estimate the shape and scale parameters of a Weibull distribution from a sample data using MLE. I checked the WeibullDistribution class of Apache commons Math but it doesn't have such functionality. Any suggestion? I need to use the class in my java application.

在Apache Commons Math中没有直接计算Weibull分布的MLE估计的方法,但是既然你知道了规模和形状的估算方程,你可以使用Apache Commons Math的类NewtonRaphsonSolver的方法solve()来计算估计形状参数,使用Newton-Rhapson方法,而对于比例,我认为你可以在得到形状的结果后使用Sum类的evaluate()方法。
