Question

Quizplus · Accepted Answer

High leverage observations are those with extreme values of X. Therefore, option B is correct. Unusual values of Y might indicate outliers, not necessarily high leverage observations. A large standardized residual might suggest an outlier, but again, not necessarily a high leverage observation. High correlations between the X values indicate multicollinearity, which is not related to leverage.
