An Analytical Investigation of the Effects of Heterogeneous Regression Slopes in Analysis of Covariance.
Hollingsworth, Holly H.
Educational and Psychological Measurement, v40 n3 p611-18 Fall 1980
If heterogeneous regression slopes are present in analysis of covariance (ANCOVA), the likelihood of committing a Type I error is greater than what had been prespecified. The power of the ANCOVA test of hypothesis for all possible differences of treatment effects is not maximized. (Author/RL)
