The ZIP includes all sixteen examples, engine code, pinned statistical and decimal-arithmetic dependencies, their licences, unit tests and an independent Python reference checker. Node 20 or later and Python 3.11 or later are sufficient; no network access, package installation or account is needed to run the kit.
Redistribution boundary
Original calculation code and synthetic inputs are MIT licensed. Simple Statistics retains its ISC licence and Decimal.js retains its upstream MIT notice. Referenced papers, external market data and proprietary provider methods are not part of the kit. The model cards remain available individually as JSON from their own pages.
