A module for manipulating insurance loss triangles

Bermuda

Bermuda is a Python package for the representation, manipulation, and exploration of insurance loss triangles, created by Ledger Investing. It offers a user-friendly interface for:

• Loading and saving insurance loss triangles using a number of formats (e.g. JSON, CSV, Pandas DataFrame objects, binary files).

• A single Triangle class for manipulating triangles of varying complexities (e.g. ragged, multi-program, cumulative or incremental triangles).

• An intuitive Cell type that can hold multiple data types and metadata.

• A collection of useful Cell- and Triangle-level functionality, including summarizing, aggregating, extending, filtering, and bootstrapping insurance loss triangles.
