solow-duration

Survival / duration analysis for the Solow statistical-computing stack.

• [SurvfuncRight] — the Kaplan–Meier (product-limit) estimator of a right-censored survival function, with Greenwood standard errors.
• [PHReg] — Cox proportional-hazards regression estimated by maximizing the Breslow partial log-likelihood, exposing coefficients, standard errors, z-statistics, p-values and the partial log-likelihood.

Both estimators are cross-validated against golden reference values frozen in tests/fixtures/duration.json.
