models for random hypergraphs with a given degree sequence
Despina Stasi, Kayvan Sadeghi, Alessandro Rinaldo +2
We introduce the beta model for random hypergraphs in order to represent the occurrence of multi-way interactions among agents in a social network. This model builds upon and gener…
Goodness-of-fit for log-linear network models: Dynamic Markov bases using hypergraphs
Elizabeth Gross, Sonja Petrović, Despina Stasi
Social networks and other large sparse data sets pose significant challenges for statistical inference, as many standard statistical methods for testing model fit are not applicabl…
Fibers of multi-way contingency tables given conditionals: relation to marginals, cell bounds and Markov bases
Aleksandra B. Slavković, Xiaotian Zhu, Sonja Petrović
A reference set, or a fiber, of a contingency table is the space of all realizations of the table under a given set of constraints such as marginal totals. Understanding the geomet…
