Question

Quizplus · Accepted Answer

Data points with high leverage have a strong influence on the fitted regression model and can greatly impact the estimated coefficients. These data points are referred to as influential points and should be carefully examined before finalizing the regression model. Therefore, choice C - influential - is the best answer. Residuals and sum of squares error are not related to high leverage points.
