y. Buchanan's Reform party membership increased from 1996 to 2000 by 110% in Palm Beach county. Comparing 1996 to 2000, there's no evidence of widespread error or fraud. Rich Ulrich wrote: > > On Thu, 09 Nov 2000 17:22:25 GMT, Peter Lewycky <[EMAIL PROTECTED]> > wrote:

1) The ballot form was made public and widely distributed well in advance of the election. The print was larger than normal to assist the elderly. The ballot was a single page. If they had used a conventional list then it would've been two pages long (possibly with Gore on the second page). Both

The other problem is that the networks are competitive. Statisticians and pollsters are more guarded, but the media wants to make a definitive statement NOW. A lot is at stake for getting the news-breaking story and headline out first. "J. Williams" wrote: > > It appeared at first it was Gore

I've often been called upon to do a t-test with 5 animals in one group and 4 animals in the other. The power is abysmally low and rarely do I get a p less than 0.05. One of the difficulties that medical researcher have is with the notion of power and concomitant sample size. I make it a point of c

It happens all the time in medicine. If I can show a p value 0.05 or less the researchers are delighted. Whenever I can't produce a p of 0.05 or less they start looking for another statistician and will even withhold a paper from publication. "Simon, Steve, PhD" wrote: > > In a post to EDSTAT-L

Consider generating a normal distribution N(mean, var) and the numbers will be fractional eg -2.346, -0.998, 0.445, etc. Multiply by 1000 (or whatever is required) to convert to whole numbers. Then you can add or subtract (whole numbers) to center the distribution. Variance will be 1000^2*var. So

The original question was how to come up with a unique identification that would be known only to the respondent and would be remembered. As long as they put in 4 Latin characters followed by 6 Arabic numbers (that could pass for a date ... I don't check). Maybe they used their girl friend's name
