I referred in my reply to a paper by Diaconis and Sturmfels. The exact
reference is:
Diaconis and Sturmfels, Algebraic algorithms for sampling from conditional
distributions, Ann. Stat 26 (1998) 363-397.
They cite the following:
Besag and Clifford, Generalized Monte Carlo significance tests, Biometrika
76 (1989) 633-42.

Exact Maximum Likelihood Package
...ould like to create a link between Singular (or any other CAS)
and R. The problem of MLE computation is just one instance of the
benefits that symbolic computations has to offer to statisticians.
For a more detail account of this interaction, you can check the
articles written by Pachter and Sturmfels that will be published in
Science
http://math.berkeley.edu/~lpachter/papers.html
In those articles it is explained how computational algebra can be used to
help in many problems of Computational Biology, like Sequence Analysis.
MY PROBLEM IS THAT I JUST STARTED LEARNING R. I really don't kn...

My name is Michela Marignani and I'm an ecologist trying to solve a problem
linked to knight' s tour algorithm.
I need a program to create random matrices with presence/absence (i.e. 1,0
values), with defined colums and rows sums, to create null models for
statistical comparison of species distribution phenomena.
I've seen on the web many solutions of the problem, but none provides
