Abstract: | We consider geometrically regular statistical models defined by local densities of probability measures corresponding to discrete
or continuous time Markov processes and smoothly depending on a finite dimensional parameter. Evolution equations are derived
in terms of the generators of the underlying Markov additive processes for the elements of the related Fisher information
matrix and the skewness tensor defining the Riemannian metric and the Amari-Chentsov's affine α-connections as functions of
time and starting points of Markov processes.
