An Empirical Investigation of the Effects of Heterogeneous Regression Slopes in Analysis of Covariance
Hamilton, Basil L.
Educational and Psychological Measurement, 37, 3, 701-12, Aut 77
The effects of the violation of the assumption of homogeneity of regression on the Type I error rate and on the power of analysis of covariance are investigated. The results indicate that analysis of covariance is robust when sample sizes are equal. (Author/JKS)
