MATHEMATICAL ENGINEERING TECHNICAL REPORTS Use of Primal-Dual Technique in the Network Algorithm for Two-Way Contingency Tables

The network algorithm of Mehta and Patel is one of the most efficient algorithms to execute a generalized Fisher’s exact test in two-way contingency tables. In this article an efficient algorithm for solving the longest path problem in the network algorithm is proposed. The efficiency of the proposed algorithm relies on the primal dual technique for convex network flow problems and the use of m...

MATHEMATICAL ENGINEERING TECHNICAL REPORTS Markov chain Monte Carlo tests for designed experiments

We consider conditional exact tests of factor effects in designed experiments for discrete response variables. Similarly to the analysis of contingency tables, a Markov chain Monte Carlo method can be used for performing exact tests, when large-sample approximations are poor and the enumeration of the conditional sample space is infeasible. For designed experiments with a single observation for...

MATHEMATICAL ENGINEERING TECHNICAL REPORTS Fibers of sample size two of hierarchical models and Markov bases of decomposable models for contingency tables

We study Markov bases of hierarchical models in general and those of decomposable models in particular for multiway contingency tables by determining the structure of fibers of sample size two. We prove that the number of elements of fibers of sample size two are powers of two and we characterizes the primitive moves of Markov bases in terms of connected components of a certain graph defined fr...
