ReliaGrowR 0.6
New Features
- New
nhpp() function for fitting parametric
Non-Homogeneous Poisson Process (NHPP) models (Power Law and Log-Linear)
to recurrent event data from repairable systems, including
piecewise/segmented support with automatic change point detection.

mcf() function for non-parametric Mean Cumulative
Function estimation using the Nelson-Aalen estimator.
- New
exposure() function for computing system exposure
(total operating time at risk) across repairable systems.
- New
overlay_rga() and overlay_nhpp()
functions for overlaying multiple model fits on a single plot.
