Re: statistical similarity of two text

Sorry, Cantor: this is not possible, in general. One can discover whether two (or more) things _differ_ (on some quantitative measure) at a specified significance level (when this is a reasonable thing to do -- it isn't always reasonable), but the formal definition of significant in statistical analysis does not permit discovering whether two (or more) things are _similar_. However, it may suffice for your purposes to discover that two things are not different enough that you can tell them apart (which is not the same thing as discovering that they are the same), on whatever measure (or set of measures) you choose to analyze. Whether this be a useful outcome or not depends heavily on how much information you have (that is, on the size of the sample available) on the things being compared. In any case, the hard part is defining the characteristics, or properties, or measures, on which the two texts/articles are to be compared. Donald F.

Re: EdStat: Probabilistic inference in resampling?
In article [EMAIL PROTECTED], Robert J. MacG. Dawson [EMAIL PROTECTED] wrote: Herman Rubin wrote: I consider the Fisherian one to be the only relevant one. In fact, I do not think it goes far enough; at best, probability is a property of the real world like length and mass. On the contrary: length and mass are abstractions that approximately describe certain aspects of the real world (quantum mechanics demonstrates this.) They can also both be used, advan- tageously, to describe other aspects of the real world other than those that we normally associate with them (for instance, dimensional analysis makes good use of the fact that the natural dimension of capacitance is length...) I should have said that probability should be an assumed property of the real world like length and mass. Abstract models are mental; they are not derived from the real world, but rather selected if they fit. Einstein (I do not have the reference) was one of the few to see that this is the case. Probability works like that too. Mathematically probability is very simple and paradox-free; it exists only in the sense that 24-dimensional quaternionic space or the Monster Group exist. Various real-world things behave in roughly the same way: both long-run frequencies (the frequentist application of probability theory to the real world) and degrees of belief subject to certain mental disciplines that individuals may or may not adhere to (the Bayesian application). The frequentist application depends heavily on strong prior assumptions. The assumption of independent trials with the same probability is effectively untestable; at best, it is approximately true, but we act as if this approximation holds very far out in the tails. The frequentist view of testing is even more questionable. (It is undoubtedly true that in the real world a person may well believe incompatible things. The word believe is not the3 property of the statistical community and we cannot say oh no you don't to such a person. However, those whose degrees of belief in related events do *not* fit the Bayesian yoga and who are prepared to bet when the odds give them an edge according to their own beliefs can be reliably (in the long run) relieved of their stakes. This gives some objective basis to the idea of consistent belief systems.) -Robert Dawson = Instructions for joining and leaving this list and remarks about the problem of INAPPROPRIATE MESSAGES are available at http://jse.stat.ncsu.edu/ = -- This address is for information only.

I am not at all convinced of a difference. Sporting statistics still seem to me to be exactly the same as parallel tests in psychology. Team stats, I agree, might seem MORE or LESS parallel - more parallel, since the means have to be the same. But UP for one has to be DOWN for another. Exactly like homers, the IQ score in May is not exactly the same as January, except by coincidence. If you were scanning a group, you would expect RTTM in either instance, exactly as described by the correlation, etc. dmr every individual player could get better the 2nd half of the season ... or, get worse ... in terms of batting ... [ ... ] To be sure: I was referring to performance *in* a 2nd half, and not as statistics that are cumulative. - History says, a big change is less likely for baseball than for a psych-test. If you take your parallel IQ test several months apart, I suppose you could sprain-a-brain in the meantime. Or drop out of school and miss the test entirely. You can read in the sports page that a team has caught fire or is in the slumps. However, so far as I have seen, the longest streaks are amazingly consistent with chance. I have seen estimates, for the major US professional sports. The estimates for individual streaks are not beyond chance, either. (Some of these were in articles published in the ASA journal named Chance, over the last several years.) -- Rich Ulrich, [EMAIL PROTECTED] http://www.pitt.edu/~wpilib/index.html = Instructions for joining and leaving this list and remarks about the problem of INAPPROPRIATE MESSAGES are available at http://jse.stat.ncsu.edu/ =
Symposium 2001 of Statistics Canada
Statistics Canada is holding its 18th International Symposium on Methodological Issues from October 16 to October 19, 2001, in Hull, Quebec, just minutes away from Ottawa. The theme of Symposium 2001 is Achieving Data Quality in a Statistical Agency: a Methodological Perspective. This symposium will provide an ideal forum for statisticians, researchers, academics, data analysts and persons interested in meeting the challenges of a statistical agency to discuss, exchange knowledge and share experiences. Three workshops will be held on October 16th. They are Non-sampling Errors by Clyde Tucker of the Bureau of Labor Statistics, USA; An Overview of Statistical Quality Control Methods Used in Statistical Agencies by Walter Mudryk of Statistics Canada; and Implementing Continuous Quality Improvement in a Statistical Agency by David Marker and David Morganstein of WESTAT, USA. Visit www.statcan.ca/english/conferences/symposium2001 where you will find the Symposium 2001 Program and the Registration Form.
