Integration of new techniques

[genedan]

I came across this thread in the CAS General Research forum regarding a few new papers. Since one of our goals was to have this package be at the forefront of actuarial open source, I figured we could collect novel (or older, but not-yet-implemented) techniques in a table, which will be updated as they are discussed and prioritized.

Technique: A name or short-description of the technique
Reference: A link to a paper which details the technique
Difficulty: How hard it would be to implement the technique in chainladder-python
Demand: Public demand for including the technique in the package.

Technique	Reference	Difficulty	Demand
Richman-Wüthrich Individual Claims Reserving	https://arxiv.org/pdf/2602.15385, https://arxiv.org/pdf/2603.11660	TBD	TBD
Frequency-Severity Techniques	https://www.casact.org/sites/default/files/database/studynotes_friedland_estimating.pdf	Low	Medium
Benktander Golden Stairs	https://www.tandfonline.com/doi/full/10.1080/03461238.2025.2536811?af=R#d1e108	TBD	TBD

Thanks for featuring the first one!

we probably need that migration to tabular backend before we can comfortably tackle no. 1

no. 2 is already possible today. let me know if you want some code snippets.

no. 3 looks doable. always a good sign to have data right in the paper
