可汗学院:统计学(视频版)

So our F statistic which has an F distribution--and we won't go real deep into the details of the F distribution.

因此,我们的 F 统计量具有 F 分布——我们不会真正深入研究 F 分布的细节。

可汗学院:统计学(视频版)

So I'm not going to go into a lot of the guts of the F statistic, but we can already appreciate that each of these Sum of squares has a Chi-squared distribution.

所以我不打算深入探讨 F 统计量的很多内容,但我们已经可以理解这些平方和中的每一个都具有卡方分布。

可汗学院:统计学(视频版)

10 -- which means that if we assume the null hypothesis, there is less than a 10% chance of getting the result we got, of getting this F statistic, then we will reject the null hypothesis.

F检验 F-test

(重定向自F statistic)

F检验F-test),最常用的别名叫做联合假设检验英语:joint hypotheses test),此外也称变异数比率检验方差齐性检验。它是一种在零假设(null hypothesis, H0)之下,统计值服从F-分布的检验。其通常是用来分析用了超过一个参数的统计模型,以判断该模型中的全部或一部参数是否适合用来估计母体。

F检验这名称是由美国数学家兼统计学家George W. Snedecor命名,为了纪念英国统计学家兼生物学家罗纳德·费雪(Ronald Aylmer Fisher)。Fisher在1920年代发明了这个检验和F分配,最初叫做变异数比率英语:Variance Ratio)。

英语百科

F-test F检验

(重定向自F statistic)

An F-test is any statistical test in which the test statistic has an F-distribution under the null hypothesis. It is most often used when comparing statistical models that have been fitted to a data set, in order to identify the model that best fits the population from which the data were sampled. Exact "F-tests" mainly arise when the models have been fitted to the data using least squares. The name was coined by George W. Snedecor, in honour of Sir Ronald A. Fisher. Fisher initially developed the statistic as the variance ratio in the 1920s.
