The following columns are added to the PValues data table when the Robust option is selected in the launch window. The Robust option only applies when Y is continuous, so Robust column cells are empty when Y is categorical. See Fit Robust in the Basic Analysis book for additional details about Huber M-estimation. For an example, see Example of Robust Fit.
