摘要: 根据母体分布假设的x~2检验理论,提出了求x~2变量最小值点估计母体分布参数的方法。对任何一元、二元随机变量,只要给出母体分布概率密度函数的一般表达式,都可以用该方法估计出母体分布参数。

Abstract: According to x2 testification theory of population distribution hypothesis, a method of estimating population parameters through searching for the minimum value point of x0 variable was presented. It was shown that population parameters could be estimated for any one-dimensional or two-dimensional random variable by this method, only if its probability density function exists
