devtools::install_github("adibender/pammtools")pammtools offers various utilities and convenience functions that
facilitate working with Piece-wise exponential Additive Mixed Models (PAMMs).
To get started, see the Articles section.
An overview over the packages functionality is given in
- Andreas Bender and Fabian Scheipl, 2018: "pammtools: Piece-wise exponential Additive Mixed Modeling tools", arXiv eprint, 2018, https://arxiv.org/abs/1806.01042
For a tutorial-like introduction to PAMMs see:

A general framework for the representation and estimation of cumulative effects (or exposure-lag-response associations) is described in:
