华德·亚伯来罕(Abraham Wald)在1950死于飞机失事,他的名字将与统计决定论永远联在一起.这一理论在比较近代的数理统计中,可列为三个伟大进展之一.这些进展中的第一个是小样理论的推广,由高适(W.S.Gosset)开始,但是主要的功绩在活着的统计学家中应当归于高年的费煦爵士(Sir Ronald Fisher).他们得到中值的准确分布,方差的准确分布,相关系数以及其他子样参数的准确分布,虽然有些只是对由某种类型的总体中得来的子样而言.并算出表来使得实验统计学家有了一整套的技术如 t 测验,F 测验,方差分析等等.这套技术自从出现了以后一直为实验统计学家所乐于使用的.第二个进展是估计及假定测验的理论,与乃门(J.Neyman)及皮尔生(E.S.Pearson)特别联爵一起.他们建立了信念区间的概念.统计学家的主要兴趣是认为在虚无假定的测验,譬如两个观察的
Abraham Wald died of a plane crash in 1950, and his name will be forever associated with statistical determinism, which, in modern mathematical statistics, ranks as three great advances One of the first of these developments was the promotion of the theory of the sample, starting with the WSGosset, but the main merit of the living statisticians was Sir Sir John Ronald Fisher, The exact distribution of the median, the exact distribution of the variance, the correlation coefficients, and the exact distribution of the other subsample parameters, although some are only for subsamples derived from one type of population, and the tables are calculated to enable the experimental statisticians There is a complete set of techniques such as t-test, F-test, analysis of variance, etc. This technique has been used by experimental statisticians since its inception. The second is the theory of estimation and hypothesis testing, J. Neyman and ESPearson, who built the concept of belief interval, the main interest of statisticians is that in the null hypothesis tests, such as the two observed
