  1. MANOVA • Control of experimentwise error rate (problem of multiple tests). • Detection of multivariate vs. univariate differences among groups (multivariate responses). • Analysis of repeated measures (e.g. growth curves) AGR206

  2. Multivariate differences AGR206

  3. Partition of SS AGR206

  4. MANOVA • Model assumptions and analysis strategies. • Interpretation of output. • Identification of group differences. • Identification of variables involved in group differences. AGR206

  5. MANOVA Assumptions • Independence of errors. • Homogeneity of variance-covariance matrices. • Normality. • No outliers. AGR206

  6. MANOVA and Path • Combination of manova and path analysis allows us to partition not only the variance, but also the covariance of the response variables into treatment and residual. AGR206
