Linear structural equation models postulate noisy linear relationships between variables of interest. Each model corresponds to a path diagram, which is a mixed graph with directed edges that encode the domains of the linear functions and bidirected

In multivariate statistics, acyclic mixed graphs with directed and bidirected edges are widely used for compact representation of dependence structures that can arise in the presence of hidden (i.e., latent or unobserved) variables. Indeed, under mul

Die vorliegende Arbeit beschäftigt sich mit statistischer Inferenz in invarianten graphischen Modellen mit Normalverteilungsannahme. Hierbei handelt es sich um Verteilungsfamilien, die zwei Arten von Restriktionen berücksichtigen. Zum einen spiegel

The distribution of the maximum likelihood estimator of the covariance matrix in a class of invariant Gaussian graphical models is determined and seen to belong to the class of generalized Riesz distributions. For testing two nested models, the distr

Ternary decision rules are analyzed that allow for abstentions, in addition to Yea- and Nay-votes. The German Bundesrat serves as a prime example. We show that the decision-making efficiency of the Bundesrat would increase if abstentions were allowed
