WebThe Fisher information attempts to quantify the sensitivity of the random variable x x to the value of the parameter \theta θ. If small changes in \theta θ result in large changes in the likely values of x x, then the samples we observe tell us a lot about \theta θ. In this case the Fisher information should be high. WebIn statistics, the observed information, or observed Fisher information, is the negative of the second derivative (the Hessian matrix) of the "log-likelihood" (the logarithm of the likelihood function). It is a sample-based version of the Fisher information. Definition. greek prefix for death
