方差分析（Analysis of Variance，ANOVA）是一种统计方法，用于检验三个或更多样本均值是否存在显著差异。它基于方差的概念，通过比较样本内（组内）和样本间（组间）的变异来确定不同组之间是否存在显著差异。ANOVA可以帮助我们理解不同因素对结果变量的影响。罗纳德·费希尔（Ronald Fisher）在20世纪初开发了方差分析方法...

方差分析Analysis of variance
Analysis of Variance a statistical method in mathematics for determining the effect of separate factors on the result of an experiment. Analysis of variance was first proposed by the British statistician R. A. Fisher in 1925 for analyzing results of agricultural experiments designed to reveal under ...
In subject area: Computer Science Analysis of Variance (ANOVA) is a statistical technique used to compare the means of two or more groups. It calculates the F-statistics and p-value for each feature to estimate the ratio of between-group variability to within-group variability and determine the...
