WebA covariate-dependent approach to Gaussian graphical modeling as described in Dasgupta et al. (2024). Employs a novel weighted pseudo-likelihood approach to model the conditional dependence structure of data as a continuous function of an extraneous covariate. The main function, covdepGE::covdepGE(), estimates a graphical representation of the conditional … WebJun 3, 2016 · 1 Answer. We know that Γ ( r, λ) = 1 Γ ( r) λ r x r − 1 e − λ x if x ≥ 0 . In this case the likelihood function L is. By apllying the logaritmic function to L we semplificate the problem so. and now we must find the point of max of l o g L, so ∂ L ∂ λ = − T + n r λ = 0 which have as solution λ ^ = n r T.
