IBNR with the Loss Ratio Method using the ChainLadder package

ChainLadder is a package for the R statistical environment that contains various functions for performing loss reserving for Property/Casualty/General Insurance. Mostly, the package's functions are intended to implement sophisticated stochastic models, but many simpler, deterministic methods are relatively easy to perform using helper functions in the package. This post will demonstrate how to calculate IBNR with the Loss Ratio Method.

IBNR with the Chain-Ladder Method using the R ChainLadder package

ChainLadder is a package for the R statistical environment that contains various functions for performing loss reserving for Property/Casualty/General/Non-Life Insurance.
