Carlson, James E. – 1980
The multivariate analysis of variance approach to the analysis of data from repeated measures designs that include covariates is reviewed and contrasted with univariate methods. Assumptions necessary for meaningful interpretation of the results of the multivariate analysis are discussed and contrasted to those of the univariate approaches. An…

Experimenters sometimes wish to estimate for a particular dependent variable the proportion of total group variance that is associated with mean differences among fixed treatments or subject classifications. Hays (1981) represents this proportion by the parameter omega squared. A point estimate may be easily computed as a function of the number of…
