Webdistribution acts like a Gaussian distribution as a function of the angular variable x, with mean µand inverse variance κ. This example can be generalized to higher dimensions, where the suﬃcient statistics are cosines of general spherical coordinates. The resulting exponential family distribution is known as the Fisher-von Mises distribution. ionia meat locker

In mathematical statistics, the Fisher information (sometimes simply called information ) is a way of measuring the amount of information that an observable random variable X carries about an unknown parameter θ of a distribution that models X. Formally, it is the variance of the score, or the expected value of the observed information. The role of the Fisher information in the asymptotic theory of maximum-likelihood estimation wa… WebJan 17, 2024 · Fisher information of poisson distributed random variable.
