WebFeb 10, 2024 · where X is the design matrix of the regression model. In general, the Fisher information meansures how much “information” is known about a parameter θ θ. If T T is an unbiased estimator of θ θ, it can be shown that. This is known as the Cramer-Rao inequality, and the number 1/I (θ) 1 / I ( θ) is known as the Cramer-Rao lower bound. WebFisher Matrix Lifan Wang The Fisher Matrix is useful in estimating the errors of a parameter set of an experiment without actually knowing or tting the the parameter values. This is widely used in de ning the observational strategies of an experiment. 1 The Basics Consider rst a simple case: suppose we observe a series of quantities y b, b 2f1
