delta.calculate         Calculates the rank-based test statistic for Y
                        and S and the difference, delta
delta.calculate.extension
                        Calculates the rank-based test statistic for Y
                        and S and the difference, delta, accomodating
                        paired data and allowing for a two-sided test
est.power               Estimated power to detect a valid surrogate
example.data            Example data
example.data.highdim    Example data for the high-dimensional functions
rise.evaluate           Performs the evaluation stage of RISE:
                        Two-Stage Rank-Based Identification of
                        High-Dimensional Surrogate Markers
rise.screen             Perform the screening stage of RISE: Two-Stage
                        Rank-Based Identification of High-Dimensional
                        Surrogate Markers
test.surrogate          Tests whether the surrogate is valid
test.surrogate.extension
                        Tests whether the surrogate is valid, extended
                        to the paired, two sided test setting
test.surrogate.rise     Performs RISE: Two-Stage Rank-Based
                        Identification of High-Dimensional Surrogate
                        Markers
