Studentized residuals are the raw residuals divided by an independent estimate of the residual standard deviation. The residual for observation i is divided by an estimate of the error standard deviation based on all observations except for observation i. s r i = r i M S E ( i ) ( 1 − h i i ) , where MSE(i) is the mean squared error.

The correlation coefficient r indicates the straight line relationship of a set of paired. The calculation of a standard deviation involves taking the positive.

We apply the lm function to a formula that describes the variable eruptions by the variable waiting, and save the linear regression model in a new variable eruption.lm. Then we compute the residual with the resid function. > eruption.lm = lm( eruptions ~ waiting, data=faithful) > eruption.res = resid(eruption.lm). We now plot.
