QUANTREG Procedure

If you specify multiple quantiles in a MODEL statement, additional analyses, such as those specified in the TEST statement, are now produced for each quantile specified.

The RANKSCORE option in the TEST statement enables you to perform rank tests. Available score functions provide normal scores, Wilcoxon scores, and sign scores, which are asymptotically optimal for the Gaussian, logistic, and Laplace location shift models, respectively.
