Development Triangle

Create a development triangle model and run suite of tools

A development triangle is a table that shows changes in the value of various cohorts over time. Development for any of these cohorts (for example, accident year claims) is the change in the value for the cohort over time.

Objects

Mean Square Error of Prediction for Estimated Ultimate Claims
This example shows a workflow for estimating ultimate claims using a developmentTriangle object with simulated reported claims and then calculating the corresponding mean square error of prediction (MSEP).
Bootstrap Using Chain Ladder Method
This example shows how to apply a chain ladder bootstrap method to generate several developmentTriangle objects to estimate the ultimate claims.
