Cohen's f2 multiple regression
WebCohen's f2 is one of several effect size measures to use in the context of an F-test for ANOVA or multiple regression. Its amount of bias (overestimation of the effect size for the ANOVA) depends on the bias of its underlying measurement of variance explained (e.g., R2, η2, ω2 ). The f2 effect size measure for multiple regression is defined as: WebPower for Multiple Regression Analyses Beginning with his seminal article, Multiple Regres sion as a General Data-AnalyticSystem, Cohen (1968) has repeatedly …

It is used when we want to predict the value of a variable based on the value of two or more other variables. The variable we want to predict is called the dependent variable (or sometimes, the outcome, target or criterion variable). The variables we are using to predict the value ...
