基于Mathematica的F分布表的计算方法

Computing Algorithm of F-distribution Table Based on Mathematica

研究了F分布的上分位点Fα(n1,n2)的性质,指出了利用Mathematica软件提供的函数直接计算Fα(n1,n2)的缺陷,提出了计算Fα(n1,n2)的自定位二分算法,此算法可以求出比查表更广泛的数值,计算结果稳定可靠,方便实用,填补了在Mathematica软件里计算Fα(n1,n2)的空白.

In this paper, the property of F-distribution value Fa （ n 1, n 2） is researched. Having studied the computation of F, （n1 n2） by functions built in Mathematica, the fault of the computing method is pointed out. The auto-oriented binary algorithm is proposed, and the algorithm is stable and convenient.
