Abstract

We describe portable software for estimating and simulating a nonhomogeneous Poisson process whose rate function is exponential and may include a polynomial or a sinusoidal component. Program NPPMLE computes maximum-likelihood estimates of the rate-function parameters from a series of event epochs. Given the rate-function parameters, program NPPSIM simulates the process via a thinning scheme.
