openactuarial

One install for the full OpenActuarial ecosystem.

PyPI Python

Overview

openactuarial is a meta-package: it contains no code of its own and exists to install the seven OpenActuarial packages in one step. The ecosystem covers general actuarial workflows — experience analysis, projection, rating and pricing, loss modeling, tail estimation, and portfolio simulation — as small packages that share conventions and compose across seams.

Installation

pip install openactuarial

Requires Python 3.10 or newer.

openactuarial pins exact versions of every package: each release installs the one combination that was tested together as a release train. If you want looser version ranges, install the individual packages instead — they declare compatible ranges (>=X.Y,<X.Y+1) rather than exact pins. Each package can also be installed individually (pip install actuarialpy, and so on).

What gets installed

Package Role
actuarialpy Calculation primitives, the canonical Experience data contract, and the ExperienceSet workbook layer (one construction call over source tables)
experiencestudies Experience reporting, actual-vs-expected, claimant and concentration analysis
projectionmodels Claim, premium, and expense projection over a renewal horizon
ratingmodels Manual and experience rating, credibility, indication, GLM relativities
lossmodels Severity and frequency fitting, aggregate loss distributions; fits directly from a claims-listing Experience
extremeloss Extreme-value tails: POT/GPD, GEV, return levels, splicing; fits directly from a claims-listing Experience
risksim Portfolio Monte Carlo, dependence, reinsurance contracts, risk measures

Version policy

Dependencies are declared as open floors, so pip install openactuarial resolves to the latest release of every package. Cross-package compatibility is exercised nightly by the ecosystem smoke workflow, which reruns every package's test suite against current PyPI releases. For reproducible environments, pin the individual packages in your own requirements or constraints file.
