+abstract: This package provides both R functions for working with primary event censored
+  distributions and Stan implementations for use in Bayesian modeling. Primary event
+  censored distributions are useful for modeling delayed reporting scenarios in epidemiology
+  and other fields. It provides support for arbitrary delay distributions, a range
+  of common primary distributions, and allows for truncation and secondary event censoring
+  to be accounted for.
