Package index • ProfileLadder

Core Functions

The key functions of the ProfileLadder package that implement three functional-based nonparametric (point) reserve prediction algorithsms, the overall distributional reserve prediction implemented in the permutation bootstrap resampling, and the prediction of the next running diagonal (so-called 1-year-ahead prediction).

parallelReserve(): Parallel Based Development Profile Reserve

mcReserve(): MACRAME Based Development Profile Reserve

permuteReserve(): Permutation Bootstrap Reserve (PARALLAX, REACT, MACRAME)

predict(<profileLadder>): One-year-ahead prediction based on PARALLAX, REACT, or MACRAME

Utility Functions

Supporting functions that help to handle run-off triangle data and allow some functionality between the ProfileLadder package and the ChainLadder package.

as.profileLadder(): S3 Method Class profileLadder

incrExplor(): Exploration of Run-Off Triangle Increments

mcBreaks(): Access Markov Chain Breaks for Run-Off Triangle Increments

mcStates(): Access Markov Chain States in the MACRAME Algorithm

mcTrans(): Access Markov Chain Transition Matrix in the MACRAME Algorithm

observed(): Observed Run-Off Triangle Layout vs. Predicted (Unknown) Layout
