Synthetic data

The data

The Meridian Re datasets the examples read: what each file holds and which chapter uses it. All of it is synthetic, generated from a fixed seed, and none of it is real.

Everything in data/ is generated deterministically by generate_data.py from a fixed seed, ensuring byte-for-byte reproducibility on any fresh clone. No proprietary company data or real mortality tables appear anywhere in this work.
