Query: Algebraic statistics, tables, and networks: The Fienberg advantage   Stephen Fienberg's affinity for contingency table problems and reinterpreting
models with a fresh look gave rise to a new approach for hypothesis testing of
network models that are linear exponential families. We outline his vision and
influence in this fundamental problem, as well as generalizations to
multigraphs and hypergraphs.
