A Monte Carlo Study of Analysis of Covariance under Violations of the Assumptions of Normality and Equal Regression Slopes.
Levy, Kenneth J.
Educational and Psychological Measurement, v40 n4 p835-40 Win 1980
Analysis of Covariance (ANCOVA) is robust with respect to dual violations of the assumptions of equal regression slopes and normality of distributions provided that group sizes are equal, but displays disruptions of empirical significant levels when unequal regression slopes and unequal group sizes are coupled with nonnormal distributions.
