Fisher information of function of parameter
WebMar 31, 2024 · Shannon information measures the information we will get "after" the coin is tossed keeping the parameter constant while Fisher information determines the information of the variability of the parameters itself so maybe the variance in parameter for biased coin could be 0.6,0.65,0.7 etc so does Fisher information measure that? … WebThe Fisher information matrix with respect to the log–Cholesky parameterization is I ...

WebMar 1, 2024 · The Fisher Information Matrix (FIM) plays an important role in the theory of statistical inference, and it measures the amount of information the observed data carries about unknown parameters. It essentially measures the overall sensitivity of the log-likelihood function to changes in the parameters.
