+t-scores).  The proportion of null values and the parameters of the null
+distribution are adaptively estimated from the data.  In addition, the package
+contains functions for non-parametric density estimation (Grenander
+estimator), for monotone regression (isotonic regression and antitonic
+regression with weights), for computing the greatest convex minorant (GCM) and
+the least concave majorant (LCM), for the half-normal and correlation
+distributions, and for computing empirical higher criticism (HC) scores and
+the corresponding decision threshold.")
