arcstat
Arc-length statistics: goodness of fit, distributions, and a Bayesian test — one shared, pure-C
back-end, bound identically from R (package arcstat) and Python (this package).
The C sources are compiled on first import; there are no third-party dependencies.
Three tools
- Goodness of fit — a test based on the arc length of the probability plot, with an analytic
saddlepoint null, sensitive to local density structure (multimodality, clustering, heaping) that the
Kolmogorov–Smirnov, Cramér–von Mises and Anderson–Darling tests miss:
al_statistic,al_pvalue,al_moments. - Distributions — build a distribution from the arc length of its defining curve: the quantile
arc-length family and its L-moment fitting:
arcq_qd,arcq_arclength,sample_lmoments. - Bayesian test — a Dirichlet-process / Bayesian-bootstrap arc-length goodness-of-fit test:
bb_post_disc,bb_ref_disc,bb_evidence.
import arcstat
arcstat.al_pvalue(1.567, 50) # saddlepoint p-value
arcstat.arcq_arclength([0.3, -0.2], 1.5) # arc length of a quantile curve
arcstat.bb_evidence(u) # Bayesian evidence against H0
The same C sources back the R package arcstat, and the two return identical values.
