Query: Markov Bases for Typical Block Effect Models of Two-way Contingency
  Tables   Markov basis for statistical model of contingency tables gives a useful tool
for performing the conditional test of the model via Markov chain Monte Carlo
method. In this paper we derive explicit forms of Markov bases for change point
models and block diagonal effect models, which are typical block-wise effect
models of two-way contingency tables, and perform conditional tests with some
real data sets.
