Bermuda

Bermuda is a Python package for the representation, manipulation, and exploration of insurance loss triangles, created by Korra. 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.

If you’re new to Bermuda, take a look at the Quick Start guide for a brief overview of its functionality, or the User Guide for a more complete explanation of Bermuda’s design decisions, insurance triangles, and Bermuda’s overall architecture. The Tutorials section includes common usage patterns.
