WebIn this section, we learn the distinction between outliers and high-leverage observations. In short: An outlier is a data point whose response y does not follow the general trend of the rest of the data.; A data point has high leverage if it has "extreme" predictor x values. With a single predictor, an extreme x value is simply one that is particularly high or low.
