Effects of Heterogeneous Regression Slopes on the Robustness of Two Test Statistics in the Analysis of Covariance.
Wu, Yow-wu B.
Educational and Psychological Measurement, v44 n3 p647-63 Aut 1984
The present study compares the robustness of two different one way fixed-effects analysis of covariance (ANCOVA) models to investigate whether the model which uses a test statistic incorporating estimates of separate unequal regression slopes is more robust than the conventional model which assumes the slopes are equal.
