"Probability, Statistics, and Truth" by Richard von Mises is available in paperback [ISBN 0-486-24214-5] and might be just what you seek. >A discussion of how the quantum world may have >different laws of statistics might be a plus. The statistical portion of statistical mechanics is fairly simple, and no different conceptually from other statistics. = Instructions for joining and leaving this list and remarks about the problem of INAPPROPRIATE MESSAGES are available at http://jse.stat.ncsu.edu/ =

This would appear to be an effect due to the fondness of Americans for the word "every", which seems to get itself inserted unnecessarily into "seven out of every ten statistical statements". = Instructions for joining and leaving this list and remarks about the problem of INAPPROPRIATE MESSAGES are available at http://jse.stat.ncsu.edu/ =

Look at the complementary event: what is the probability P that exactly N - x distinct objects have not been selected? Then the probability you seek is 1 - P . >Yes, I'v already thought of that. But the complement probability is also >hard for me. Can you help me? Let x be fixed; when you make one pick of n objects out of N distinct objects, what is the probability that none of N - x distinct objects has been selected? Replace the n objects, mix well, and pick again. What is the probability that none of those same N - x distinct objects has been selected? Repeat this procedure k times. = Instructions for joining and leaving this list and remarks about the problem of INAPPROPRIATE MESSAGES are available at http://jse.stat.ncsu.edu/ =

I haven't seen a Combinatorics course in a college class schedule in nearly twenty years, but combinations and their probabilities are still taught in Statistics courses [perhaps not with as much emphasis as previously]. = Instructions for joining and leaving this list and remarks about the problem of INAPPROPRIATE MESSAGES are available at http://jse.stat.ncsu.edu/ =

Time Series Data. Significant movement

Nine months of weekly measurements comprise only 39 data; surely that's not too great a number to display at once. >My question is, Is there a statistical way of selecting the set of >measurement that show movement up or down other than just >eye balling the graphs?? If by "movement up or down" you mean "trend", then there are a great many methods of detecting and displaying trend, none of which require a selection of any subset of only 39 data. = Instructions for joining and leaving this list and remarks about the problem of INAPPROPRIATE MESSAGES are available at http://jse.stat.ncsu.edu/ =
