Conversation
Relocate the example from gist_tides/ to gists/tides/ and append the complete tides_nns.py inside a collapsible block in the README so it can be replicated without opening a second file.

Fix a grammar slip, reframe "gist" wording as "example" now that it lives in the repo, and keep the savefig comment in sync between the script and its embedded copy. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01MxVLKYqazC2uuAW3P3MbAm

Summary
Adds a self-contained example,
gists/tides/, that reproduces Lord Kelvin's tide forecast from the raw water-level series using NNS.ARMA — no astronomy or hand-tuned harmonic constituents. Achieves R² ≈ 0.965 on a held-out two-week window.Inspired by John Mount's Lord Kelvin, Data Scientist.
Contents
tides_nns.py— runnable script (~2 min, dominated byNNS.ARMA.optim).README.md— historical framing, results, a note on the one non-obvious line (filter seasonal periods before slicing), and the full script embedded in a collapsible block for copy-paste replication.tides_forecast.png— generated figure.Notes
ruff check(the example is covered by the repo-wide lint).nnspackage or tests.🤖 Generated with Claude Code
