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)
    <doi:10.1023/B:LIDA.0000012424.71723.9d>, Matthews & Farewell (1982)
    <doi:10.2307/2530460>), Exponential-Lindley (Joshi & Rattihalli (2020)
    <doi:10.1007/978-981-15-5414-8_29>), Lindley (Joshi, Jose, & Bhati (2016)
    <doi:10.1080/03610918.2015.1096381>), log-logistic (Nadar, Upadhyay, &
    Joshi (2025) <doi:10.3390/math13091457>), and Weibull (Williams & Kim
    (2013) <doi:10.1080/03610926.2011.600505>) 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.
