# 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`.
