As of Version 7.0, StudentizedResiduals has become a property of LinearModelFit.
- To use StudentizedResiduals, you first need to load the Regression Common Functions Package. You can do this by using Needs["LinearRegression`"], which will automatically load the Regression Common Functions Package, or you can load the package directly by using Needs["RegressionCommon`"].
- StudentizedResiduals gives the fit residuals divided by their jackknifed variance estimates.
- StudentizedResiduals is equivalent to FitResiduals/Sqrt[JackknifedVariance (1 - HatDiagonal)].
