This simply implies that your (median) estimate of a is less than 1. >meaning can be attached to 'a'. Here Y is output and Xs >are input variables Where?

John Tukey
-- Forwarded Message: From: "Wainer, Howard" <[EMAIL PROTECTED]> Subject: John Tukey Dear Friends and colleagues, John Wilder Tukey died last night of an accumulation of physical problems. We shared a mince pie (his favorite) on Monday night in his hos- pital room, and he was in good spirits, but in the end his body failed him. He left us with his mind intact; despite the physical problems that plagued him, in the end he was still John Tukey. If you have any specific question please write and I will try to answer them. As other plans are made I will keep you informed.

Example of Poisson random variable
A casino that I frequent has a "bad beat" jackpot in its poker room. Without going into all the rules, suffice it to say that the chances of anyone's hitting the jackpot within any two minute interval is probably of the order 10**-6. In other words, hitting the jackpot can definitely be construed as a rare event. The jackpot had not been hit in about four months, until last weekend, when it was hit two times in 12 hours. This phenomena has happened before--several months without being hit, then bam, it is hit twice in a few hours. Isn't this a characteristic of a Poisson process? A very rare event goes a long time without occurring, then it occurs several times within a short period. Could one test the hypothesis of this "bad beat" jackpot following a Poisson distribution using a goodness-of-fit test?? = Instructions for joining and leaving this list and remarks about the problem of INAPPROPRIATE MESSAGES are available at http://jse.stat.ncsu.edu/ =

In particular, he was the *last* "World's Greatest Statistician". At the turn of the 20th century, the title could be said to belong to Karl Pearson. By the first third, it had passed to Sir Ronald Fisher. By mid- century, the honor was Tukey's. No one had his command of both theory and practice, and given the way the field has fractured and split apart into so many specialties, it seems no one will ever again command such depth at such breadth. = Instructions for joining and leaving this list and remarks about the problem of INAPPROPRIATE MESSAGES are available at http://jse.stat.ncsu.edu/ =
Help: Batch Statistical Graphing Script Language
Hi, Perhaps someone can help me, I hope this isn't too off-topic. I'm looking for a Statistical Graphics scripting language which I can use on an NT or Unix server to describe and batch (rather than interactively) produce GIF output for a web site. Does such a beast exist? Freeware prefered. Thank you very much, Mark W. Humphries --- Got questions? Get answers over the phone at Keen.com.

I was fortunate enough to sit in on a short course at Iowa State 20 or so years ago and hear his spirited discussions with some of the professors there. Prior to that I had no idea that people could be passionate about the field of statistics.
