Perturbation of matrices and non-negative rank with a view toward statistical models
Cristiano Bocci, Enrico Carlini, Fabio Rapallo
In this paper we study how perturbing a matrix changes its non-negative rank. We prove that the non-negative rank is upper-semicontinuos and we describe some special families of pe…

Markov bases and subbases for bounded contingency tables
Fabio Rapallo, Ruriko Yoshida
In this paper we study the computation of Markov bases for contingency tables whose cell entries have an upper bound. In general a Markov basis for unbounded contingency table unde…
