The screenshot below shows a Pluto.jl notebook that replicates basic universal life policy mechanics, but hooks into the rich DiffEq/SciML ecosystem that Julia has. With that, one could perform many types of analysis of the behavior of the dynamical system that is a modern life insurance product. This type of approach may be too "heavy" for most workflows, but may be worth investigating.
Because JuliaActuary doesn't have a beefy server to run this on and let anybody run/visualize thousands of stochastic scenarios, for this one you have to run it locally. This notebook hooks into a lot of dependency packages so may take a moment to run the first time you open.
Open a Julia REPL and copy and paste the following:
# install these dependencies import Pkg; Pkg.add(["Pluto","Plots","MortalityTables", "DifferentialEquations","ActuaryUtilities","ColorSchemes"]) # use and start Pluto using Pluto; Pluto.run()
