A reseаrcher fоund а stаndardized residual fоr a specific оbservation equaled -2.87. The researcher was deciding whether to keep the observation in the model. He wanted to know if it was influential and calculated the leverage with the following data: The data set had 10 observations and the mean of x was 69.5.
