%description
Simulates events from one dimensional nonhomogeneous Poisson point
processes (NHPPPs) as per Trikalinos and Sereda (2024,
<doi:10.48550/arXiv.2402.00358>). Functions are based on three algorithms
that provably sample from a target NHPPP: the time-transformation of a
homogeneous Poisson process (of intensity one) via the inverse of the
integrated intensity function (Cinlar E, "Theory of stochastic processes"
(1975, ISBN:0486497996)); the generation of a Poisson number of order
statistics from a fixed density function; and the thinning of a majorizing
NHPPP via an acceptance-rejection scheme (Lewis PAW, Shedler, GS (1979)
<doi:10.1002/nav.3800260304>).
