dfr.dist 0.1.0

Initial release.

Features

• dfr_dist() constructor for creating distributions from hazard functions
• Complete distribution interface: hazard(), cum_haz(), surv(), cdf(), pdf(), inv_cdf(), sampler()
• Likelihood model interface: loglik(), score(), hess_loglik(), fit()
• Support for right-censored survival data
• Numerical integration for cumulative hazard
• Inverse CDF sampling

Examples

Supports modeling complex hazard patterns:

• Exponential (constant hazard)
• Weibull (monotonic hazard)
• Bathtub curves (infant mortality + useful life + wear-out)
• Proportional hazards with covariates
