摘要
利用Beta分布与F分布之间的关系,获得了一种基于二阶展开求解F检验临界值的迭代算法,并给出具体算例证实了这是一种较为快速而行之有效的方法。
In this paper,an iterative algorithm for evaluating criticalvalue of F-test based on two order expanding is obtained by means of the relation between Beta and F distibution functions.It is proved by an example that our method is quick and effective in practice.
