WebOct 20, 2024 · In order to obtain Jeffrey's prior we find the second derivative with respect to λ using the above. ∂ 2 ∂ λ 2 log p ( y ∣ λ) = ∂ ∂ λ ( − n + 1 λ ∑ i = 1 n y i) = − λ − 2 ∑ i = 1 n y i Now taking the expected value and using the fact that if y ^ ∼ Poisson ( λ), then E [ y ^] = λ we obtain E [ ∂ 2 ∂ λ 2 log p ( y ∣ λ)] = − λ − 2 n λ = − n λ WebOct 20, 2024 · Analytical form of Jeffrey's prior.
