Fisher's score
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. WebApr 23, 2024 · You do a Fisher's exact test on each of the 6 possible pairwise comparisons (daily vs. weekly, daily vs. monthly, etc.), then apply the Bonferroni correction for multiple tests. With 6 pairwise comparisons, the P value must be less than 0.05 / 6, or 0.008, to be significant at the P < 0.05 level.

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 ...
