WebThe " general linear F-test " involves three basic steps, namely: Define a larger full model. (By "larger," we mean one with more parameters.) Define a smaller reduced model. (By "smaller," we mean one with fewer parameters.) Use an F-statistic to decide whether or not to reject the smaller reduced model in favor of the larger full model.

WebAug 16, 2024 · An ANOVA (“analysis of variance”) is used to determine whether or not the means of three or more independent groups are equal..
