# Tutorials

Executable, end-to-end tutorials covering every public feature of normix. Each
page runs against the current source at build time, so the code and outputs you
see are always in sync with the library.

The tutorials are grouped into five tracks. **Core** builds the conceptual
foundation; **Distributions** tours every class; **EM** covers fitting in
practice; **Statistics** adds model comparison and goodness of fit; and
**Finance** applies everything to real market data.
