MANOVA in R – How To Implement and Interpret One-Way MANOVA
WebThe general purpose of multivariate analysis of variance (MANOVA) is to determine whether multiple levels of independent variables on their own or in combination with one another … WebIt computes power for three MANOVA test statistics: Wilks’ lambda, Pillai-Bartlett trace, and Hotelling-Lawley trace. MANOVA is an extension of common analysis of variance (ANOVA). In ANOVA, differences among various group means on a single-response variable are studied. In MANOVA, the number of response variables is clifton college school sports
