cyclomort
packageR
The cyclomort
package provides tools for modeling and
analysis of periodic mortality (or other time-to event) processes from
right-censored data. The package was inspired by the need to detect
annual seasonal patterns in mortality of wildlife, thus, the central
assumption is that the period itself is known (e.g. 1 year, 24 hours,
etc.), but the number, intensity and duration of the peaks of increased
hazard are unknown. The central function estimates these parameters from
right-censored data. Other functions allow for simulation, visualization
of fits, and a priori hypothesis testing tools.
Examples are provided in the package vignette
Also - for fun - a blog post!
To install from GitHub:
library(devtools)
install_github("https://github.com/EliGurarie/cyclomort", vignettes = TRUE)
This project is fairly mature, and will soon be uploaded to CRAN, but GitHub is a good place to report issues for further development.
