1引言我们在文[1]中阐明了总体分布和总体分布特征的内涵,并以频率稳定于概率的原理和古典概型知识为基础,介绍了用样本频率直方图估计总体直方图的原理.本文将在文[1]的基础上,进一步考虑一类特殊变量的总体分布估计问题,该类变量能够依据问题背景完全确定其值域,且值 1 Introduction We clarify the connotations of population distribution and population distribution in [1]. Based on the principle of frequency stability in probability and the knowledge of classical generalization, we introduce the principle of estimating population histogram with sample frequency histogram. Based on [1], this paper further considers the problem of estimating the overall distribution of a special class of variables that can completely determine their range based on the problem context, and the value
