<p>I'm the author of a Linux Journal <a href="http://www.linuxjournal.com/article/6467" rel="nofollow">article</a> that proposed some statistical spam filtering ideas that ended up on fairly widespread use (SpamAssassin, SpamSieve, SpamBayes, and others). These are mathematical ideas, but my formal training in math is quite limited. I have a B.A. in math, no advanced degree. And by the time I creating writing math- and statistics-oriented algorithms, I'd forgotten such details has how to integrate. I picked up some statistical techniques from a college class (years after graduating and forgetting most of the statistics I'd learned in college), and have been self-taught beyond that, and have gotten help for things I don't know how to do -- usually involving integration. That help is greatly appreciated!</p>
