Package: flexhaz Title: Dynamic Failure Rate Distributions for Survival Analysis Version: 0.5.2 Authors@R: person("Alexander", "Towell", , "queelius@gmail.com", role = c("aut", "cre"), comment = c(ORCID = "0000-0001-6443-9897")) Description: Flexible framework for specifying survival distributions through their hazard (failure rate) functions. Define arbitrary time-varying hazard functions to model complex failure patterns including bathtub curves, proportional hazards with covariates, and other non-standard hazard behaviors. Provides automatic computation of survival, CDF, PDF, quantiles, and sampling. Implements the likelihood model interface for maximum likelihood estimation with right-censored and left-censored survival data.
