Looking for a crash course in math

Markov Chains. Got a website? Got a book? I'm looking for the "Idiot's Guide", not analytical proofs.

Bit late.

It's a tool that looks useful in geography, I just have to learn about it's parameters. I have downloaded some papers that apply to the type of stuff I do but I am looking for more. This forum has an amazing bunch of people. Sometimes it's like drawing on an encyclopedia.

Invest in a copy of Mathcad, and even you'll be able to do it!

I'm guessing that my old HP11c doesn't do that

That's a good description of my course through math. . . . .I crashed, crashed and burned.

Don't need mathcad or maple or whatever to do the math. It's not difficult on Excel, which is what I was doing this weekend. I'm looking for insight as it may apply to geographical changes over time.

Then try this:

http://www.fh-kiel.de/fileadmin/data/wirtschaft/Dozenten/Thiemer__Andreas/MCD/markov.pdf

If I was writing a program to do it in VB Net, I'd use that as a model, it should work just as well with Excel VBA, altho for something like that if I was doing an Office XP thing, I'd do it using a combination of Access and Excel, but you would have to know how to address one as an object within the other, usually as an Excel VBA program to manage the graphs, addressing an Access data object which would manage the matrices.

Your comment on the desire to use Excel over Mathcad is much like a farmer extolling the virtues of manure over ammonium nitrate. Get with the times.

My hourly charges are always rounded, so do not send me a fractional payment again this time.

I didn't extoll the virtues of Excel, merely said that it isn't necessary to or convenient at this point to go to a math program. Hell, we have a fairly complete suite of math and stats programs on the LAN. Like I said, it isn't the tool I need (Ii have plenty) but an understanding of how the tool maybe used in a particular field.

Looking for pedagogy, not Craftsman.

Ok, then look at this one. There are some downloadable xla (Excel Add-ins) and a lot of detail on how they were constructed, I think at one point it goes off into VBA land, but I bet you would find it usefull:

based on what you have been saying, I would wager what you are looking for is right here:
