MANOVA (module 2) (Steps (Barletts test of sphericity (H0 (covariances…

- - - - calculate residuals per group per var
        
        Sum of squares
        
        covariation
        
        multiply residuals and sum them
        
        Total sums of squares and cross products matrix
        
        T
        
        T-matrix
  - - - use Estimated marignal means as group estimates
    - - no confounding
  - - - covariances are zero
    - - several univariate anova's
  - - - at least one group scores differently on at least on dependent variable
  - - - variation
    - - covariation
    - - E matrix
  - - - default
      - multiply p by m(nr of dep var) - 1
      - pairwise comparisons
- - - - HE-1
        
        ratio explained and unexplained (co)variation
- - - - examine univariate normality per variable
    - - n>14
  - - - equal sample size
    - - box test
        
        sensitive to normaility assumption
- - - - most robust against violation of multivariate normality assumption
      - most powerful
- - - - Gives amount of explained variance per variate
    - - H0: groups do not differ on the variates
    - - weight coefficients
      - Done with z scores
      - How strongly original dependent is involved in construction of variate
    - - Correlation variates and orignial dep var
    - - means of groups on variates
- - - - nr. of groups - 1
      - amount of dependent variables
  - - - more chance that groups differ
- - - - If no correlation, lower power
