Webinvolves finding p∗(θ) that maximizes the mutual information: p∗(θ) = argmax p(θ) I(Θ,T) (3) We note that defining reference priors in terms of mutual information implies that they are invariant under reparameterization, since the mutual information itself is invariant. Solving equation (3) is a problem in the calculus of variations. WebFisher information is meaningful for families of distribution which are regular: 1.Fixed support: fx: f(xj ) >0gis the same for all . 2. @ @ logf(xj ) must exist and be nite for …
