Yule biography George Yule senior married Henrietta Peach Pemberton who was the daughter of Captain Robert Boilean Pemberton of the Indian Army. The Yule family had a strong reputation for scholarship, with the grandfather of the George Udny Yule of this biography, William Yule, being a renowned scholar in Persian and Arabic. Yule returned from Germany to London in the summer of 1893 and was offered a post as a demonstrator in University College, London, by Karl Pearson. www-groups.dcs.st-and.ac.uk /~history/Biographies/Yule.html   (2405 words)

George Udny Yule George Yule developed his approach to correlation via regression with a conceptually new use of least squares. Yule worked at University College London where he was promoted to Assistant Professor of Applied Mathematics in 1896. Yule's early work is on waves but as Pearson began to work on statistics Yule was more and more drawn into that field. www.shsu.edu /~icc_cmf/bio/yule.html   (285 words)

m3028 In 1899 G. Udny Yule published what is considered to be the first example of a modern multiple regression analysis in Correlation coefficients are identical to 3 decimal places except for one big discrepancy (OUTRATIO X PROPOLD, where Yule has 0.167 vs. recalculated value of 0.109). Yule does not test for the significance of coefficients (no t-tests), and the (inverse) measure of fit he uses seems to be the standard error of estimate divided by the standard deviation of Y (PAUP). www.unc.edu /~nielsen/soci709/data/yule.htm   (193 words)

Forman.Frank,2000.A Healthy Disrespect For Authority: The New Creationism   (Site not responding. Last check: ) And I could bring up an almost forgotten 1924 paper by G. Udny Yule, one of the great English statisticians, which considered the size distribution of species in a genus and conceived the first birth and death probability process, now known by his name, to generate this skewed size distribution. Yule hypothesized that species split in two at one random rate and become extinct at another. Udny Yule, “A Mathematical Theory of Evolution, Based upon the Conclusions of Dr. J.C.

Causality: Cause & Effect In 1899, the statistician G. Udny Yule investigated the causes of pauperism in England. Yule used a regression model to analyze his data and found that the change in pauperism was positively related to the change in the proportion treated outside of poor-houses. A contemporary of Yule's suggested that what Yule was seeing was instead an example of confounding--those areas with more efficient administrations were better at both building poor-houses and reducing poverty. www.tufts.edu /~gdallal/cause.htm   (1366 words)

George Udny Yule   (Site not responding. Last check: ) Yule left each of these positions for various reasons, but no matter where he was working or who he was working with, Yule was always accomplishing something that was significant. Yule concluded, however, that the correlation between the two is sheer nonsense and its meaning has no significance at all. Without Yule's devotion and hard work, the use of probability-based statistical methods in the social sciences as well as in other disciplines would not be as advanced as it is today. www.mrs.umn.edu /~sungurea/introstat/history/w98/Yule.html   (1052 words)

Linear_regression Francis Galton studied this phenomenon, and applied the slightly misleading term 'regression towards mediocrity' to it (parents of exceptional individuals also tend on average to be less exceptional than their children). For Galton, regression had only this biological meaning, but his work (1877, 1885) was extended by Karl Pearson and Udny Yule to a more general statistical context (1897, 1903). In the work of Pearson and Yule, the joint distribution of the dependent and independent variables is assumed to be Gaussian. www.news-from-newspapers.com /en/Wikipedia.org/2005/04/14/Linear_regression.html   (2119 words)

Mutationism - Wikipedia, the free encyclopedia The resolution that led to the Modern Synthesis, which resurrected the view of Darwin using a different mechanism, came slowly. Udny Yule argued that a trait reflecting effects of multiple Mendelian characters could show a normal distribution. Even though most fluctuations are environmental, some of the continuous variability of natural species could have a genetic basis, and if sufficiently abundant, this could serve as the basis for a Mendelian mechanism allowing Darwinian gradualism. en.wikipedia.org /wiki/Mutationism   (921 words)

Yule His father, Sir George Udny Yule, was a member of the Bengal Civil Service and was knighted for his work in India while his mother was a daughter of a Captain of the Indian Army. Yule grew up and received his education in London since the age of four, when his family left Scotland and moved there. Yule spent a couple years as a pupil in engineering works before he decided that he did not want to be an engineer in 1892. www.econ.hku.hk /~wsuen/immortal/yule.htm   (395 words)

Science in Christian Perspective He objects to harrison's failure to consider the work of Yule which concerned itself with the legitimacy and limitations of using word-count to establish authorship. Yule posits that adequate statistical analysis in prose would require a piece at least ten thousand words long. Grayson and G.

Super Stardom It is because the class of distributions represented by the expression (1) was first derived by G. Udny Yule, that this distribution carries his name. Since the main thrust of this paper is to examine whether the Yule distribution can describe the relative number of finance, accounting or economics articles published by an author, we portray the process in such a context. This statistical test shows that the frequency pattern of the Yule distribution, as shown in Panel D of Table 1, is significantly different compared to the actual publishing patterns of the authors displayed in Panels A, B and C in Table 1. www.westga.edu /~bquest/1997/super.html   (2941 words)

Statistical Laboratory: History In 1912 a University Lectureship in Statistics was established to which G. Udny Yule was appointed, working in the Faculty of Agriculture. Yule was already the author of a very influential textbook (An Introduction to the Theory of Statistics, Griffin, 1911), but is now remembered for his subsequent work in time series analysis. Yule was succeeded on retirement in 1931 by John Wishart, arriving from Rothamsted. www.statslab.cam.ac.uk /History/2history.html   (15176 words)

George Udny Yule George Udny Yule was born near Haddington, and studied civil engineering at University College London, and later also physics at Bonn University. Yule was very influential in the fledgling discipline of statistics, and an active member of several scientific societies, but he also had an interest in medieval devotional literature, and studied Latin in later life, alongside motoring and flying. Yule left all his books to St John's to dispose of, and there are currently over 200 items which bear his provenance. www.joh.cam.ac.uk /library/special_collections/early_books/pix/provenance/yule/yule.htm   (455 words)

Cost Abstract   (Site not responding. Last check: ) This study examines the existence of the superstar phenomenon using a stochastic model developed by G. Udny Yule and Herbert A. Simon. This model states that the probability mechanism underlying the editor's choice of an author's articles and predicts that author's outputs (articles) will be concentrated among a few lucky individuals.

Yule-Walker Equations and Algorithms for Their Solution William Meeker has a useful class note which introduces AR(p) models and discusses the Wolfer sunspot data that was analyzed by Yule (1927) in the world's first use of an autoregressive model. As Katz's notes in his lecture, Yule considered only the case AR(2), but in this note Meeker also discusses the models for p=3, 4, etc. In this series the maximum occurs in 1957, and one sees that there is much more to be found than just the well-know approximate period of 11.1 years. www-stat.wharton.upenn.edu /~steele/Courses/956/Resource/YuleWalkerAndMore.htm   (689 words)

Thought this might be of interest... A cursory glance at the data indicates that one cannot treat these as a sample from a single population, even if the comedies, tragedies, and historical plays are separated; there is a definite effect of the individual work. As far as I remember, the editor had a Slavic-type name beginning with `G'; a grep of the library's entire author index makes J. Gvozdanovic the most likely option (listed for another book in the general area of linguistics, but unconnected to the topic under discussion), but this id is tentative for now. Analyses covered include comparisons of (1) word-length spectra (and a number of statistics calculated from them); (2) sentence-length spectra (which are found to follow a log-normal distribution for any particular text by a single author. www.ibiblio.org /bgreek/archives/greek-3/msg00351.html   (3504 words)

Reasons to challenge digital fingerprint evidence The inspector in effect told the examiner: "We know this guy shot the victim and this is the gun he used. The contamination here can be quite crude; the investigator or prosecutor might be signaling to the examiner that a more inculpatory result is desired and inviting the examiner to rethink the conclusions with that in mind. On a less crude level, a man being charged with the murder of a police officer claimed that the officer was beating him and that he took the [*40] officer's gun in self-defense and shot the officer. www.clpex.com /Articles/ObserverEffectsinForensicScience.htm   (14646 words)
