Enhanced Implementation of Whittaker-Henderson Smoothing R package WH version 2.0.0 CRAN Task View: ActuarialScience (https://CRAN.R-project.org/view=ActuarialScience) An enhanced implementation of Whittaker-Henderson smoothing for the graduation of one-dimensional and two-dimensional actuarial tables used to quantify Life Insurance risks. 'WH' is based on the methods described in Biessy (2025) <doi:10.48550/arXiv.2306.06932>. Among other features, it generalizes the original smoothing algorithm to maximum likelihood estimation, automatically selects the smoothing parameter(s) and extrapolates beyond the range of data.
