Abstract




The rhotau embedding of a parametric statistical model defines both a Riemannian metric, called "rhotau metric", and an alpha family of rhotau connections. We give a set of equivalent conditions for such a metric to become Hessian and for the +/ 1connections to be dually flat. Next we argue that for any choice of strictly increasing functions rho(u) and tau(u) one can construct a statistical model which is Hessian and phiexponential. The metric derived from the escort expectations is conformally equivalent with the rhotau metric.
