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.
