Class library for actuarial claims reserving and tariff rating for non-life insurances

Python sibling of the R lossratio package: loss-ratio analysis and projection for long-term health insurance. Stage-adaptive projection (exposure-driven before maturity, chain ladder after), with maturity point and cohort regime detection. In development.

Open-source Python library for P&C loss reserve estimation — pip install actuarial-reserving

Burning cost analysis for P&C ratemaking: chain-ladder, Bornhuetter-Ferguson, trend estimation, premium on-leveling, Mack residuals. pip install burncost

Actuarial claims reserving model using Chain Ladder and Bornhuetter–Ferguson methods to estimate ultimate losses and IBNR reserves from a loss development triangle.
