摘要
工程上很多数据都服从截尾分布,文中介绍了以χ2值构造非线性极小化问题模型来求解截尾分布参数及确定分布类型的方法,并通过算例证明该方法的可行性。
Considering many data in engineering generally obeyed cutting-tail distribution, a method for cutting-tail distribution parameter estimation and confirm its distribution type which was solved by constructing nonlinear unconstraint minimum x^2 value model was introduced, and it was proved to be available by the computing case.
