+The provided features include: summary statistics, two-sample tests, rank
+tests, generalised linear models, cumulative link models, Cox models,
+loglinear models, and general maximum pseudolikelihood estimation for
+multistage stratified, cluster-sampled, unequally weighted survey samples;
+variances by Taylor series linearisation or replicate weights;
+post-stratification, calibration, and raking; two-phase subsampling designs;
+graphics; PPS sampling without replacement; principal components, and factor
+analysis.")
