WebFisher Information. Fisher information (fi) is defined (Kay, 1993), under mild regularity conditions on the distribution of ξ, for the parameter θ, as (11)Iξ(θ):=−Eξ(Δθθ⁢ log⁢p(ξ θ)⁡)=Eξ(( θlog⁡p(ξ θ))( θlogp(ξ θ)T) ... β → j d, λ → j d, respectively, of a single generalized Gamma distribution. Consequently, it ... 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.
