v0.4.17 — Learn case-study redesign
Completes the Explore → Analyze → Learn trilogy: the Learn surface is rebuilt as a single-pass tutorial — "the ideas behind the case study" — in lockstep across the website, the Colab notebook, and the Streamlit app.
Learn
- The Learn page is now a single-pass tutorial that opens by interpreting a real two-way fixed-effects Kuznets model (
.interpret()/.explain()), browses the full 27-topic concept index (list_topics) grouped by theme, then isolates each idea in a simulated sandbox where the truth is known: the within-transformation identity, why fixed effects matter, two inference classics, convergence, and the Kuznets wave. Everylearn_*sandbox appears once each, removing the old tour/gallery duplication and adding the previously-undemonstratedlearn_kuznets_waves. - The Learn Streamlit app mirrors the tutorial — the Concept sandboxes page grows from seven to nine tabs (adding
learn_sigma_convergenceandlearn_convergence_clubs), reordered to the case-study sequence; the explainers page browses all 27 topics. - The Learn Colab notebook is regenerated so the website, notebook and app present the same sequence.
