Data assimilation web site
Dear list members, I would like to draw your attention on the Data Assimilation in Hydrological and Hydrodynamic Modelling web site: http://projects.dhi.dk/daihm The project aims at implememting data assimilation in different domains of water science. You will find there our latest publications and results. We also make available the DAIHM Matlab toolbox, that provides a set of tools for data assimilation and ensemble modelling. The toolbox has been developed in link with groundwater modelling but can be applied in any domain. Your comments and suggestions are welcome. Best regards.

Re: What is the difference between Statistics and Mathematical

Courses called Mathematical Methods of Physics are common, and some courses are called Mathematical Physics even though they are really methods courses. But these are not true mathematical physics courses. It IS true that most physics courses are theoretical courses, and that physical theory is always formulated mathematically. It is NOT true that these courses are Mathematical Physics courses, because such are courses where one proves mathematical theorems, usually involving functional analysis, Lie groups/algebras, differential geometry, category theory, et al. This is a matter of terminology. There are few mathematics courses, unfortunately, which prove theorems. Probably most mathematics majors are college juniors before having to prove a theorem themselves. I would not be all that surprised if physics majors knew mathematical concepts at least as well as mathematics majors. If you compare the journals Communications in Mathematical Physics and Journal of Mathematical Physics with, say, the Physical Review or the European Physical Journal, you will see that Mathematical Physics and Physics per se are distinct from each other. -- This address is for information only.

For testing goodness of fit to a distribution, the chi-squared test has very low power. If there are parameters to be estimated, the asymptotic distribution is not chi-squared, but can be calculated numerically fairly easily by using the moment generating function as an analytic function. One thing about empirical distributions is that they may not be one of the standard forms. This is why the Jackknife method and then later the Bootstrapping methods were developed. Thus you can extract the distribution for your data set. Tests like the chi-squared test, the Kolmogorov-Smirnov test, the Cramer-von Mises test, can test fit to a parametric family, or whether two samples come from the same distribution. If the forms are not standard, one can compare the deviation with samples form the assumed distribution; this is far better than anything like the jackknife or the bootstrap, and does not require asymptotics to be used. There is no way that anyone can extract the analytic form of a distribution from which data has been sampled from a finite amount of data. -- This address is for information only.

Statistical illiteracy in Assoc. Press
Today's story from the Associated Press, Study: American kids getting fatter at disturbing rate. By 1998, nearly 22 percent of black children ages 4 to 12 were overweight, as were 22 percent of Hispanic youngsters and 12 percent of whites. ...In 1986, the same survey showed that about 8 percent of black children, 10 percent of Hispanic youngsters and 8 percent of whites were significantly overweight. ...Overweight was defined as having a body-mass index higher than 95 percent of youngsters of the same age and sex, based on growth charts from the 1960s to 1980s. ... Disturbing trends also were seen in the number of children who had a body-mass index higher than 85 percent of their peers. In 1986, about 20 percent of blacks, Hipanics and whites alike were in that category. By 1998, those figures had risen to about 38 percent of blacks and Hispanics alike and nearly 29 percent of whites. I guess that means that today's children have gotten so fat, that 100% is not enough to account for them---in1986 children required105%, and by1998 a full 114% to123% was required to account for them ;-). The only way I can make sense out of this story is if these percentages use as a baseline the 50 percentile and 85 percentile body-mass index values from the 1960s. But clearly, neither the author, or the editors, either understood or cared that what they were writing was self-contradictory on its face. Can our statistical literacy have gotten that bad? It reminds me of the story that Barry Goldwater in his 1964 Presidential campaign vowed that if he were elected, no American would make less than the national average income. -- == Lee Altenberg, Ph.D. E-mail: [EMAIL PROTECTED] == = Instructions for joining and leaving this list and remarks about the problem of INAPPROPRIATE MESSAGES are available at http://jse.stat.ncsu.edu/ =
How to beat ADHD, alcoholism, and other Addictions vefed
Do YOU need help or know somebody who needs help with any of the following addictions? alcoholism drug addiction smoking ADHD (attention hyper deficit disorder) sugar or carbohydrate bingeing PreMenstrual Syndrome,(PMS) Research has shown successfully throughout history that there is help. In 1990 Dr. Kenneth Blum discovered the gene for alcoholism. This led to amazing research in the treatment for all of the above mentioned addictions. Yes, ADHD is a form of addiction and we can prove it. Dr. Kenneth Blum is the Father of Psychiatric genetics. He is credited with discovering the gene for cocaine addiction. In 1995 he coined RDS, Reward Deficiency Syndrome, which will forever change our world. Steve Allen the media great is quoted as saying with regard to my former show where I interview the greatest minds-today I would interview Dr. Blum, whose research on the genetics of alcoholism will change the world as we see it today. Dr. Kenneth Blum who has been in private practice his entire career is finally going to help the public. He recently put global patents on 7 products that will completely change the world of addiction. His products that are 100 percent natural are finally ready. These are products that help people control their lives, that are produced by one of the most well known, most respected doctors in the medical industry. If you are interested in these products or learning about addiction on Dr. Blums new website please send me an email asap to [EMAIL PROTECTED] with the subject help or click below mailto:[EMAIL PROTECTED]?subject=help.
