Sided Bregman centroids and Jensen centroids
|

Chernoff point (Chernoff information)
|

Jensen-Shannon centroid of discrete distributions (histograms)
|

Inductive arithmetic-harmonic-mean
converging to the geometric matrix mean
|

Various centroids for bivariate normal distributions

Main features:
- Fisher-Rao manifolds: Gaussian, Multinomial, Discrete, Mixture Manifold
- Riemannian and dually flat manifolds: PSD Manifold (non-prob)
- Various dissimilarities: Bregman, Chernoff Information, Jeffreys, Skew BurbeaRao, Skew Jensen-Bregman,
Fisher-Rao , etc.
- Centroids and centers : Bregman, Skew Burbea-Rao, Gauss-Bregman center, Jeffreys-Fisher-Rao center, etc.
Visualization for points and geodesics
- Smallest enclosing ball
- Bisector
