0.1.0
First release.
- Re-export the deterministic reserving primitives from
actuarialpy.reserving
under thereservingmodelsnamespace (aliases, not copies):ChainLadder,
completion_factors,apply_completion,develop_ultimate(chain-ladder,
Bornhuetter-Ferguson, Benktander, Cape Cod),make_completion_triangle,
Mack standard errors, and the supporting helpers. - Add
BootstrapODP: the semiparametric over-dispersed-Poisson bootstrap
(England & Verrall) of the predictive reserve distribution -- estimation
error by Pearson-residual resampling, process error by a gamma draw.
Validated against Mack on the Taylor-Ashe triangle (same reserve; dispersion
phi = 52,601). - Add
ReserveDistributionwith predictive percentiles, VaR, TVaR (ecosystem
empirical estimators), and a per-origin exhibit. BootstrapODP.sample(size, rng)implements therisksimsampling seam, so a
reserve model is a portfolio component with no dependency between packages.- Add residual diagnostics:
pearson_residuals,residual_summary,
calendar_year_effects. - Add
integrations.actuarialpyto build a triangle (and a fitted bootstrap)
from a claims-listingactuarialpy.Experience. - Add reference triangles
datasets.taylor_ashe()anddatasets.raa().
