WebA key insight is that Newton’s Method and the Fisher Scoring method are identical when the data come from a distribution in canonical exponential form. Recall that f f is in the exponential family form if it has the form. f (x) = exp{ η(θ(x))x−b(θ(x)) a(ϕ) +c(x,ϕ)}. f ( x) = exp { η ( θ ( x)) x − b ( θ ( x)) a ( ϕ) + c ( x, ϕ ...

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.
