A multivariate Gaussian graphical Markov model for an undirected graph G, also called a covariance selection model or concentration graph model, is defined in terms of the Markov properties, i.e.

The β-model of random graphs is an exponential family model with the degree sequence as a sufficient statistic. In this paper, we contribute three key results. First, we characterize conditions that ...

The presentation will introduce the DACM (Dimensional Analysis Conceptual Modeling) approach as a way to represent an engineering problem in the form of oriented colored graphs. The foundations of the ...
