1. The variance around the regression line may not be constant. Hence, the equation predicts better in some ranges than in others. C. Curvilinearity. 1. The regression line may systematically underestimate in some ranges and overestimate in others because the relation between the criterion and the predictor(s) is not linear. D. Autocollinearity. 1.
