I'm looking for any tutorial documents on BNJ.  I'm trying to build on OS X , so I downloaded the SRC files, but cannot seem to get any further. 

How many of you plan to attend the Joint Statistical Meetings in Seattle this summer? Just curious. Maybe I can meet some of you. I'll be presenting a poster. :-)

Q: Why did the Bayesian reasoner cross the road?

A: You need more information to answer that question.

Hey Everone,
I'm a student at Michigan State University doing an internship for the summer. I downloaded BNJ from bnj.sourceforge.net, but the user tutorials aren't posted yet. Does anyone know where I could find some basic instruction on how to use the program?
Thanks in advance,
Rob

Have any of you guys ever used TexPoint in Microsoft Power Point? If so, have you noticed that not all of the LATEX syntax works in TexPoint?

recently I was asked by a friend on if it would be possible to build/evolve Bayes Net with Genetic Programming. I don't know how to answer it as I only know the very basic of how Bayesnet works ... What do you think ?

One of the first questions that I raise is why needs to use GP to build BN. Can a BN model be at such a difficulty level that it requires a heuristic approach such as GP ?

So here is a problem.

Imagine you have a list of cities that a salesman wants to visit, each on a particual date or range of dates.
You know, Moscow: June 1-3; Tokio: June 17; New York: June 19-25, etc. Well, technically instead of ranges I have probability distributions over the dates when the "conference" of interest for the traveling salesman occurs...

Also here is a list of transit station which the salesman can travel through: Paris, Singapour, Washington, whatever.

All these Cities can be I guess arranged in a simple graph bu what is important not every city is connected to another one, there is a network of "railroads" connecting those (I know, there is no railroad between Tokio and New York, but let it be :)). Of course those railroads have lengths (cost functions, and those are probabilistic) associated with those.

What the salesman needs is an optimal path that would make it possible to make o all those conferences or meetings by the dates specified (and i does not matter, what transition he is taking, but it should make sence in terms of lengths of the paths between those cities, that is, he should be choosing the paths hat would make "perfect timing" for him.

I am pretty sure this is a well known "classic" problem, but what is the "classic" name for the problem?
I would really appreciate if you could help me categorize the problem so that I would know where to start my search for an appropriate algorithm.

Thanks guys!

UPDATE: It appears that Hidden Markov Models (which could be actually implemented as a special case of Bayes Nets) provide a nice framework to deal with my problem.

I just needed to find out if there is any member here who is into Bayesian modeling of gene regulatory networks and cellular signaling pathways. I'd love to chat up with anyone working on the same thing.

Hi, I am new to this forum. I am a mathematical sciences major planning on taking elective statistics for the major, and hoping to get a few relevant questions answered:

Is Java a good programming language for statisticians? Numerical analysts? I noticed that this community is predicated on it.

EXTRA CREDIT-- I had a discrete mathematics exam, and I was able to probably earn partial credit on everything except this question: You have six coin tosses, and it's given that three heads and three tails are resultant. How many possible orders are there?

Hello everyone,

I'm taking the math exam to reenter the college world, as my ACT scores no longer hold any value, since they're 11 years old. I'm reading a refresher math text, but I've come across something that for the life of me, I cannot recall ever doing and cannot grasp. I'm a very logical person, so if someone can explain "Permutations" to me in a way that is utilitarian and not just a jumble of formulas, please help. Also, Pascal's triangle is baffling, and as it applies to this as well ...
