My newest article is very numbers-intensive, so will not likely appeal to most of you, but I hope that some of you guys (wait, wait, I know at least one!) who might...

"Factor Analysis" is a multivariate statistical routine that seeks to simplify complex data sets into a relatively compact model, yet retain some predictive power. I am hoping to use this and other methods to help me find useful nuggets in our sales data, like (an example) if I buy 500 pcs of X, how confident should I be in buying 200 pcs of Y if they are used in the same vehicle?

I am only an "advanced beginner" with this, I have a little training, but as they say, "a little knowledge is a very dangerous thing".

Comments and suggestions for further work are extremely welcome!
