Package: CPHazard Title: Hazard Change Point Models for Different Lifetime Distributions Version: 0.1.0 Authors@R: c(person("Vasudha", "Upadhyay", , "vasudhyay@gmail.com", role = c("aut", "cre")), person("Dr. Savitri", "Joshi", , "savitri.joshi@iiita.ac.in", role = c("aut", "cph")), person("Keerthan", "Aithal", , "aithalkeerthan@gmail.com", role = "aut")) Description: Estimates the parameters of models with a single change-point in the hazard rate for time-to-event data. Supported models include the exponential (Gijbels & Gürler (2003) , Matthews & Farewell (1982) ), Exponential-Lindley (Joshi & Rattihalli (2020) ), Lindley (Joshi, Jose, & Bhati (2016) ), log-logistic (Nadar, Upadhyay, & Joshi (2025) ), and Weibull (Williams & Kim (2013) ) hazard change-point models. Provides functions for generating random variates and evaluating the probability density function (PDF) and the cumulative distribution function (CDF) of the fitted change-point models. Includes Kaplan-Meier and Nelson-Aalen diagnostic plots, together with goodness-of-fit measures such as the Akaike Information Criterion (AIC), the Bayesian Information Criterion (BIC), distance metrics such as the L1-norm and L2-norm, and the Kolmogorov-Smirnov (K-S) statistic for model evaluation.
