Hi all!

The "numerical methods package for Squeak" reference reminds me of this rather recent proposal here:

I found Didier Besset's book 'Object-Oriented Implementation of Numerical Methods' [1] online. I think the Smalltalk code package I am looking for came from this book/author. Perhaps it was called NumericalMethods, but in searching for this package I cannot find any code. Would anyone out here know of this package? I last used it around 2002 in VisualWorks. It had all sorts of distributions and infinite series and other function classes. Pretty awesome.

I am very interested to find it in order to do coronavirus infection distributions, with a Monte Carlo simulation and using a distribution to define the delay between infection time and the onset/appearance of symptoms and finally the delay from that onset to reporting to a hospital. The goal is I want to calculate Rt [2], for NC and VA, the effective reproductive rate in time. As calculated by the founders of Instagram, NC is now below 1 [3].

I appreciate any guidance you could give me to find this software. Gotta a link? I would love it!!
