Package: TemporalHazard Title: Temporal Parametric Hazard Modeling Version: 1.2.16 Authors@R: person("John", "Ehrlinger", email = "john.ehrlinger@gmail.com", role = c("aut", "cre", "cph")) URL: https://ehrlinger.github.io/TemporalHazard/, https://github.com/ehrlinger/TemporalHazard BugReports: https://github.com/ehrlinger/TemporalHazard/issues Description: Provides native R implementations of the multiphase parametric hazard model of Blackstone, Naftel, and Turner (1986) with a focus on behavioral parity, transparent numerics, and reproducible validation against reference outputs from the original 'C'/'SAS' HAZARD program, originally developed at the University of Alabama at Birmingham (UAB). The 'SAS'/'C' code and this R package are currently developed and maintained at The Cleveland Clinic Foundation, and the R code was wholly developed at The Cleveland Clinic Foundation. The generalized temporal decomposition family extends to longitudinal mixed-effects settings (Rajeswaran et al. 2018 ). The package is intentionally implemented in pure R first; performance-critical paths may later be accelerated with 'Rcpp' without changing the public interface.
