Fisher information uniform distribution

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. The Fisher information is a way of measuring the amount of information that an observable random variable carries about an unknown parameter upon which the probability of depends. Let be the probability density function (or probability mass function) for conditioned on the value of . It describes the probability that we observe a given outcome of , given a known value of . If is sharply peaked with respect to changes in , it is easy to indicate the "correct" value of from the data, or e…
