  • Marginalization and conditioning for LWF chain graphs 

    Sadeghi, Kayvan (Institute of Mathematical StatisticsAnnals of Statistics, 2016-08)
    In this paper, we deal with the problem of marginalization over and conditioning on two disjoint subsets of the node set of chain graphs (CGs) with the LWF Markov property. For this purpose, we define the class of chain ...

  • Pairwise Markov properties for regression graphs 

    Sadeghi, Kayvan; Wermuth, N (WileyStat, 2016-11-13)
    With a sequence of regressions, one may generate joint probability distributions. One starts with a joint, marginal distribution of context variables having possibly a concentration graph structure and continues with an ...
