贝叶斯方法和频率方法比较研究

A Comparative Study on Frequency-based Method and Bayesian Method

频率学派和贝叶斯学派作为统计推理中的两个最重要的方法,对于这两种对立的研究方式的站队选择显然影响着研究者的研究活动。占有霸主地位的频率学派尽管是后来者,显然占有着优势的地位,而今年以来贝叶斯方法的复苏,重新向频率派发起挑战。文章从概率的产生作为开始,简单地介绍了统计的发展历程,并分别对这两种方法选择的实用、重要的可操作标准给予分析,认为两种方法各有利弊,对两种方法的选择应结合实际情况选择。

Bayesian method and frequency-based methods are two major methods in the study of statistical inference.The choice between these two contrasting methods apparently influences the scholar′s research work.The frequency-based method,though a latecomer,surpasses the other and occupies a dominant position,but since the beginning of this year,Bayesian method has begun to resuscitate and imposed challenges to the frequentist method.This article traces the development of statistics back to the birth of frequency and analyzes the two methods in terms of their optional utility and operational values.The conclusion drawn thereby is that they both have advantages and disadvantages,and the choice of methods between them should be in line with actual situations.
