Studentized Residual - Internal and External Studentization

The usual estimate of σ is the internally studentized residual where m is the number of parameters in the model (2 in our example). But if the i th case is suspected of being improbably large, then it would also not be normally distributed. Hence it is prudent to exclude the i th observation from the process of estimating the variance when one is considering whether the i th case may be an outlier, and instead use the e… WebStudentized residuals allow comparison of differences between observed and predicted target values in a regression model across different predictor values. They can also be compared against known distributions to assess the residual size. Studentized residuals.
