Mathematical arguments and small computations, organized into three independent tracks. Choose a track to open its reading paths and navigation.
Incerto — fat tails, extreme values, estimation, and finite-sample diagnostics.
Information Geometry — statistical manifolds, exponential families, Fisher geometry, EM, and duality.
Normix theory — the mathematics of normal mixtures, GIG/GH distributions, and latent-variable estimation.
Shared symbols live in one place: the shared notation page. New notes must reuse that canon rather than inventing parallel symbols for the same concept.
The separate Normix package documentation covers installation, implementation, and the package API.
Assumptions that are local to a note are stated there. Numerical examples illustrate calculations; they do not establish asymptotic theorems.
