Information Geometry and Statistical Manifold

Abstract: We review basic notions in the field of information geometry such as Fisher metric on statistical manifold, α-connection and corresponding curvature following Amari's work [1,2,3]. We show application of information geometry to asymptotic statistical inference.

“…Indeed, information geometry [1][2][3], which started with the seminal paper by Rao [4] has emerged from studies of invariant geometrical structure involved in statistical inference. It defines a Riemannian metric together with dually coupled affine connections in a manifold of probability distributions.…”

“…Let P be a distribution on the domain X that signifies our belief of where the optimal candidate for l resides. We assume that P belongs to the statistical manifold P [45] which is a Riemannian manifold [40] of probability distributions. Any point P ∈ P is expressed in the coordinates θ ∈ R n .…”

“…A point on an n-dimensional statistical manifold, D (from here on, we will use the symbol D to denote a statistical manifold unless specifically mentioned otherwise), can be identified with a (smooth) probability distribution function on a measurable topological space Ω, denoted by P (x; θ) [48,4]. Here, each distribution function can be parametrized using n real variables (θ…”
