On the inverse gaussian distribution function
WebDetails. The Poisson-inverse Gaussian distribution is the result of the continuous mixture between a Poisson distribution and an inverse Gaussian, that is, the distribution with probability mass function. % p (x) = \int_0^\infty \frac {\lambda^x e^ {-\lambda}} {x!}\, g (\lambda; \mu, \phi)\, d\lambda, p(x) = ∫ 0∞ x!λxe−λ g(λ;μ,ϕ)dλ, WebIn this paper we focus on Gaussian graphical models (GGM) with known graph structure, i.e, the pattern of edges is known. Our approach can also be extended to more general graphical models, including discrete distributions. For GGMs, parameter estimation essentially reduces to (inverse) covariance estimation,

Webdistributions, maximum likelihood estimation can break down. In these latter cases, the likeli-hood function is unbounded and this leads to inconsistent estimators or estimators not asymp-totically normal. It is shown that in the case of the Inverse Gaussian distribution this difficulty does not arise.
