I will discuss recent progress on the appearance of convex bodies for counting problems in real algebraic geometry, explaining a probabilistic approach to real Schubert calculus.

In this paper, we show that the Otto’s metric on a location-scale model defined on a Riemannian manifold is a warped Riemannian metric. This has been done by assuming that the location-scale model is invariant under the action of some Lie group. The obtained result is applied to the von Mises-Fisher model and to the Riemannian Gaussian model.
