اسلاید 1: MANOVA

اسلاید 2: Multivariate (multiple) analysis of variance (MANOVA) represents a blend of univariate analysis of variance principles and canonical correlation analysis. It is understood best against the backdrop of basic univariate analysis of variance (ANOVA). It is strongly related to discriminant function analysis MANOVA & DA are strongly related but conceptually distinct  Math is virtually identical -- but direction of prediction or understanding is switchedMANOVA

اسلاید 4: MANOVA vs. Discriminant AnalysisMANOVASimilar to ANOVA but deals with multiple dependent variables at the same timeCan deal with multiple factors (e.g, A, B, AXB design)Hypothesis testing procedureDiscriminant AnalysisUses multiple variables to identify group membership in categoriesUsed for single categorical grouping variableIdentifies dimensionality among group
