heteroskedasticity

it's a real word and it's my favorite. i read it in a journal article a couple of years ago, immediately wrote in on a little yellow post-it note, and stuck it on my desk so i could look at it whenever i wanted to. yes, i had to research what it meant, and no, i have not been able to use it in a conversation yet, but - and here's where it gets exciting - since i've been back in school, i've had two, count 'em, two! professors use the word. and since the semester has only begun, one has to assume i will be hearing, using, and correcting for heteroskedasticity on a regular basis. doesn't it just give you tingles?!
