- To use , you first need to load the Regression Common Functions Package. You can do this by using , which will automatically load the Regression Common Functions Package, or you can load the package directly by using .
- gives the fit residuals divided by their jackknifed variance estimates.
- is equivalent to FitResiduals/Sqrt[JackknifedVariance (1 - HatDiagonal)].
