Based on these results, we define a goodness-of-fit test for the B-EDD model and propose a family of tests for network comparisons.

We adopt a different stance by relying on a latent model where we directly model counts by means of Poisson distributions that are conditional to latent (hidden) Gaussian correlated variables.

A typical example is the joint observation of the respective abundances of a set of species in a series of sites, aiming to understand the co-variations between these species.

The multivariate distribution of the observations is supposed to follow a graphical model, whose graph and parameters are affected by abrupt changes throughout time.

We illustrate the techniques reviewed in this article on benchmarks of inference problems in genetic linkage analysis and computer vision, as well as on hidden variables restoration in coupled Hidden Markov Models.

To this aim, we restrict the set of considered graphs to mixtures of spanning trees.
