本文利用正交设计法,分析了威布尔分布中各参数所起的作用及其相互关系,提出了确定参数的“相对误差绝对值之和为最小”准则,同时,介绍了参数择优方法。
In this paper, we use the orthogonal design method to analyze the function of each parameter in Weibull distribution and its correlation, and put forward the criterion that “the sum of absolute value of relative error is the minimum” to determine the parameter. At the same time, the parameter optimization method is introduced.
