Investigate whether the Robust option makes a difference. For the Kuiper data that has been used in this chapter (don’t forget to drop some observations that are outliers!), run a basic model 20 times (for example, the type in Table 12.4). Run it 20 more times with the Robust option invoked. Characterize any differences between the results. For example, is there less variability in the R2? Is the difference between training R2 and validation R2 smaller? Now include the outliers, and redo the analysis. Has the effect of the Robust option changed?
