读《中国统计》1993年第6期于宝忠同志《对变异·变量涵义的新思考》一文(以下简称于文)颇有收益与启发,笔者认为此文既有新意又有值得商榷的地方.如在一定时间内和研究目的已定的条件下,统计总体是唯一的,说明其特征的指标的具体表现也是唯一的,它是一个常量,因此,在这种情况下,也就不存在什么变异了.这对于“所有的统计指标”都存在变异的观点来说是深入了一步.然而,值得商榷的有三点,于文认为:第一,不变标志与“变量”无缘;第二,统计指标不是变量;第三,“时间”可以作为总体和总体单位.下面谈谈自己初浅的看法.
Reading “China Statistics” No.6, 1993 In Comrade Bao Baizhong's article “A New Reflection on the Meanings of Variables and Variables” (hereinafter referred to as the article) has some benefits and inspiration. I think this article is both innovative and debatable If, within a certain period of time and for the purpose of the study, the overall statistics are unique, the indicators that characterize them are also unique in their manifestation, it is a constant, and therefore in this case it does not exist This is a step further from the viewpoint of variation in “all statistical indicators.” However, there are three issues that are debatable: the first is that the unchangeable sign has no chance of being “variable”; the second , The statistical indicators are not variables; third, “time” can be used as the overall and the overall unit.
