IntCens: Nonparametric maximum likelihood estimation for a broad class of semiparametric regression models with general interval-censored data (R).

Interval-censored data arise when the failure time of each study subject is only known to lie in an interval.
IntCens is an R software package that implements nonparametric maximum likelihood estimation (NPMLE)
for a broad class of semiparametric regression models with general interval-censored data. The current release
handles three types of failure time data:
• Univariate. Univariate failure time data described in Zeng, Mao and Lin (2016).
• Multiple Events. Failure times for multiple types of events.
• Clustered. Subjects are clustered, e.g. by family
