Statistics on Spotlight: World Statistics Day 2015
Statistics on Spotlight: World Statistics Day 2015 Shahjahan Khan Professor of Statistics School of Agricultural, Computational and Environmental Sciences University of Southern Queensland, Toowoomba, Queensland, AUSTRALIA Founding Chief Editor, Journal of Applied Probability and Statistics (JAPS), USA Email: [email protected] Abstract In the age of evidence based decision making and data science, statistics has become an integral part of almost all spheres of modern life. It is being increasingly applied for both private and public benefits including business and trade as well as various public sectors, not to mention its crucial role in research and innovative technologies. No modern government could conduct its normal functions and deliver its services and implement its development agenda without relying on good quality statistics. The key role of statistics is more visible and engraved in the planning and development of every successful nation state. In fact, the use of statistics is not only national but also regional, international and transnational for organisations and agencies that are driving social, economic, environmental, health, poverty elimination, education and other agendas for planned development. Starting from stocktaking of the state of the health of various sectors of the economy of any nation/region to setting development goals, assessment of progress, monitoring programs and undertaking follow-up initiatives depend heavily on relevant statistics. Only statistical methods are capable of determining indicators, comparing them, and help identify the ways to ensure balanced and equitable development. 1 Introduction The goals of the celebration of World Statistics Day 2015 is to highlight the fact that official statistics help decision makers develop informed policies that impact millions of people. -

Black psychologists grounded in a Black/African psychology tradition have long challenged the hegemonic paradigms and racist beliefs perpetuated by Eurocentric approaches to psychology. However, in the absence of teaching about the important contributions of Black/African psychology, many individuals remain unaware of its historical and contemporary impact on the discipline of psychology. Using the three methodological approaches of deconstruction, reconstruction, and construction as a framework, the authors identify the many ways in which Black/African psychology has challenged prevailing beliefs in psychology about Black behavior and culture and forever changed psychological research on Black people.

Correlation of Salivary Immunoglobulin a Against Lipopolysaccharide of Porphyromonas Gingivalis with Clinical Periodontal Parameters
Correlation of salivary immunoglobulin A against lipopolysaccharide of Porphyromonas gingivalis with clinical periodontal parameters Pushpa S. Pudakalkatti, Abhinav S. Baheti Abstract Background: A major challenge in clinical periodontics is to find a reliable molecular marker of periodontal tissue destruction. Aim: The aim of the present study was to assess, whether any correlation exists between salivary immunoglobulin A (IgA) level against lipopolysaccharide of Porphyromonas gingivalis and clinical periodontal parameters (probing depth and clinical attachment loss). Materials and Methods: Totally, 30 patients with chronic periodontitis were included for the study based on clinical examination. Unstimulated saliva was collected from each study subject. Probing depth and clinical attachment loss were recorded in all selected subjects using University of North Carolina‑15 periodontal probe. Extraction and purification of lipopolysaccharide were done from the standard strain of P. gingivalis (ATCC 33277). Enzyme linked immunosorbent assay (ELISA) was used to detect the level of IgA antibodies against lipopolysaccharide of P. gingivalis in the saliva of each subject by coating wells of ELISA kit with extracted lipopolysaccharide antigen. Statistical Analysis: The correlation between salivary IgA and clinical periodontal parameters was checked using Karl Pearson’s correlation coefficient method and regression analysis. Results: The significant correlation was observed between salivary IgA level and clinical periodontal parameters in chronic -
D 27 April 1936 Summary. Karl Pearson Was Founder of The
Karl PEARSON1 b. 27 March 1857 - d 27 April 1936 Summary. Karl Pearson was Founder of the Biometric School. He made prolific contributions to statistics, eugenics and to the scientific method. Stimulated by the applications of W.F.R. Weldon and F. Galton he laid the foundations of much of modern mathematical statistics. Founder of biometrics, Karl Pearson was one of the principal architects of the modern theory of mathematical statistics. He was a polymath whose interests ranged from astronomy, mechanics, meteorology and physics to the biological sciences in particular (including anthropology, eugenics, evolution- ary biology, heredity and medicine). In addition to these scientific pursuits, he undertook the study of German folklore and literature, the history of the Reformation and German humanists (especially Martin Luther). Pear- son’s writings were prodigious: he published more than 650 papers in his lifetime, of which 400 are statistical. Over a period of 28 years, he founded and edited 6 journals and was a co-founder (along with Weldon and Galton) of the journal Biometrika. University College London houses the main set of Pearson’s collected papers which consist of 235 boxes containing family papers, scientific manuscripts and 16,000 letters. Largely owing to his interests in evolutionary biology, Pearson created, al- most single-handedly, the modern theory of statistics in his Biometric School at University College London from 1892 to 1903 (which was practised in the Drapers’ Biometric Laboratory from 1903-1933). These developments were underpinned by Charles Darwin’s ideas of biological variation and ‘sta- tistical’ populations of species - arising from the impetus of statistical and experimental work of his colleague and closest friend, the Darwinian zoolo- gist, W.F.R. -
Generalized Correlations and Kernel Causality Using R Package Generalcorr
Generalized Correlations and Kernel Causality Using R Package generalCorr Hrishikesh D. Vinod* October 3, 2017 Abstract Karl Pearson developed the correlation coefficient r(X,Y) in 1890's. Vinod (2014) develops new generalized correlation coefficients so that when r∗(Y X) > r∗(X Y) then X is the \kernel cause" of Y. Vinod (2015a) arguesj that kernelj causality amounts to model selection be- tween two kernel regressions, E(Y X) = g1(X) and E(X Y) = g2(Y) and reports simulations favoring kernelj causality. An Rj software pack- age called `generalCorr' (at www.r-project.org) computes general- ized correlations, partial correlations and plausible causal paths. This paper describes various R functions in the package, using examples to describe them. We are proposing an alternative quantification to extensive causality apparatus of Pearl (2010) and additive-noise type methods in Mooij et al. (2014), who seem to offer no R implementa- tions. My methods applied to certain public benchmark data report a 70-75% success rate. We also describe how to use the package to assess endogeneity of regressors. Keywords: generalized measure of correlation, non-parametric regres- sion, partial correlation, observational data, endogeneity. *Vinod: Professor of Economics, Fordham University, Bronx, New York, USA 104 58.

What Is This Thing Called Giftedness, and How Do We Develop It? A Twenty-Five Year Perspective1 Joseph S. Renzulli This authoi provides reflections on the last 25 years of his work, focusing on the evo• lutions of models designed to help identify and meet the needs of gifted and talented students. The cited models include the Three Ring Conception of Giftedness, the Enrichment Triad Model, and the Schoolwide Enrichment Model. Summaries focus on the rationale supporting each model, including practical applications of the model in various school situations and underlying research. Also included are insights related to potential modifications and future developments of the models. The principal goal of education is to create men and women who are capable of doing new things, not simply repeating what other generations have done. —Jean Piaget— Introduction It is always a challenge to reflect upon one's work from a perspec tive of more than two decades of intense involvement, especially if your reflections will be the subject of analysis by others who have also thought long and hard about the identification and develop ment of human potential. One of the conditions for accepting this challenge of a presentation-and-critique format was that the persons whose commentary follows be asked to review the major theoreti cal papers that describe my thoughts about how we should identify and develop high levels of potential in young people. I made this request because I didn't want to repeat large amounts of what has been written elsewhere but, rather, to point out how and why my theories evolved, how the theories led to practical applications that have gained popularity in the field, and how research has helped Joseph S. -
Time Structures and the Canons of Testing
CHAPTER 6 TIME STRUCTURES AND THE CANONS OF TESTING The first article of the July 1 2009 ASCD Smart Brief was a good news story on school improvement: Math educators at a struggling Florida elementary school locked away their textbooks before the start of last year, rewriting the curriculum themselves in an approach that helped them post large gains on state tests and raised their school’s grade from a D to a B. The teachers used a problem-solving approach with games and group projects to better engage students. http://www.tampabay.com/news/education/k12/woodlawn-elementary-thinks- outside-the-book-to-pull-d-to-a-b/1014663 As is often the case, examining the newspaper article in the Tampa Bay Times (Lim, 2009) showed that there was both more and less than meets the eye. The school had tossed out its math textbooks as a part of a school improvement strategy forced by the possible penalties of the US “No Child Left Behind” program. On the one hand, a cursory examination of the three years of achievement data contained in the newspaper article showed limited improvement in most of the indicators – the differences may or may not have been significant (there were no significance tests published). The increase most profiled was an increase of “struggling students who made gains in math” from 53% to 76% between 2007 and 2008. However – and this was ignored in the text of the article – the results for 2006 were 74%, almost identical to 2008. So in this one indicator, there was a major drop over one year what was corrected in the most recent year: leaving open the possibility that this was not ‘school improvement’ but simply cohort variation. -
Page 287 PUTTING WHITEHEAD's THEORY of GRAVITATION in ITS
“07desmet” i i 2011/6/5 page 287 i i Logique & Analyse 214 (2011), 287–315 PUTTING WHITEHEAD'S THEORY OF GRAVITATION IN ITS HISTORICAL CONTEXT RONNY DESMET Introduction Alfred North Whitehead (1861–1947) is known by many for his Principia Mathematica collaboration with Bertrand Russell, and by some for his later philosophical works. This paper, however, does not focus on the mathe- matics of his Cambridge period (1880–1910), nor on the metaphysics of his Harvard period (1924–1947), but on Whitehead's involvement with relativ- ity during the London period of his professional career (1910–1924). This involvement culminated in an alternative rendering of Albert Einstein's gen- eral relativistic theory of gravitation, outlined in a number of publications, most notably in his 1922 book, The Principle of Relativity with applications to Physical Science. If one ignores the broader British reception of Einstein's physics of rela- tivity, Whitehead's alternative appears to be a creation out of nothing, and just as incomprehensible. The aim of this paper is to put Whitehead's theory of gravitation in its historical context. Like most of his British contemporaries, Whitehead only got acquainted with Einstein's 1905 special theory of relativity in the 1912–1914 time- frame, in Minkowski's format, and via the publications of, among others, Ebenezer Cunningham and Ludwik Silberstein, two men he also knew per- sonally. Whitehead wrote An Enquiry Concerning the Principles of Natural Knowledge (1919) and The Concept of Nature (1920) with the aim of con- structing the special relativistic (Minkowksi's pseudo-Euclidean) space-time from the uniform spatio-temporal texture of our sense perception. -
14 Peirce and Cartesian Rationalism DOUGLAS R
A Companion to Pragmatism Edited by John R. Shook, Joseph Margolis douglas r. anderson Copyright © 2006 by Blackwell Publishing Ltd 14 Peirce and Cartesian Rationalism DOUGLAS R. ANDERSON One of the consequences of Cartesian rationalism was its continuation of the schol- astic habit of developing philosophy around exclusionary disjunctions: certainty or ignorance, mind or body, reason or perception. If we take this habit into our examina- tions of the history of philosophy, we easily fall into a dichotomizing of philosophers: Parmenides or Heraclitus, Hume or Kant, Plato or Aristotle, and so forth. In the case at hand, we’d be tempted to begin by opposing Descartes and Charles Peirce (see Peirce). Indeed, this route is well traveled. From a Peircean perspective, however, this would be a mistake. Peirce saw himself as standing in an intellectual tradition with Descartes, as sharing interests, problems, and concerns. Thus, as we mark out the important distinctions between Peircean pragmatism and Cartesian rationalism, we must do so against the background of these shared interests. As Peirce saw it, “Descartes marks the period when Philosophy put off childish things and began to be a con- ceited young man. By the time the young man has grown to be an old man, he will have learned that traditions are precious treasures, while iconoclastic inventions are always cheap and often nasty” (CP 4.71). In the overview of Peirce’s critical engage- ment with Cartesian thought that follows, it will be important to keep in mind that Peirce saw the Cartesian tradition as a treasure even as he marked out his own dis- agreements with it. -

Should the Widest Cleft in Statistics - How and Why Fisher Oppos Ed Neyman and Pearson
School of Economics and Management TECHNICAL UNIVERSITY OF LISBON Department of Economics Carlos Pestana Barros & Nicolas Peypoch Francisco Louçã A Comparative Analysis of Productivity Change in Italian and Portuguese Airports Should The Widest Cleft in Statistics - How and Why Fisher oppos ed Neyman and Pearson WP 02/2008/DE/UECE WP 006/2007/DE _________________________________________________________ WORKING PAPERS ISSN Nº 0874-4548 The Widest Cleft in Statistics - How and Why Fisher opposed Neyman and Pearson Francisco Louçã (UECE-ISEG, UTL, Lisbon) [email protected] Abstract The paper investigates the “widest cleft”, as Savage put it, between frequencists in the foundation of modern statistics: that opposing R.A. Fisher to Jerzy Neyman and Egon Pearson. Apart from deep personal confrontation through their lives, these scientists could not agree on methodology, on definitions, on concepts and on tools. Their premises and their conclusions widely differed and the two groups they inspired ferociously opposed in all arenas of scientific debate. As the abyss widened, with rare exceptions economists remained innocent of this confrontation. The introduction of probability in economics occurred in fact after these ravaging battles began, even if they were not as public as they became in the 1950s. In any case, when Haavelmo, in the 1940s, suggested a reinterpretation of economics according to the probability concepts, he chose sides and inscribed his concepts in the Neyman-Pearson tradition. But the majority of the profession indifferently used tools developed by each of the opposed groups of statisticians, and many puzzled economists chose to ignore the debate. Economics became, as a consequence, one of the experimental fields for “hybridization”, a synthesis between Fisherian and Neyman-Pearsonian precepts, defined as a number of practical proceedings for statistical testing and inference that were developed notwithstanding the original authors, as an eventual convergence between what they considered to be radically irreconcilable. -
History of the Stanford-Binet Intelligence Scales: Content and Psychometrics
Stanford-Binet Intelligence Scales, Fifth Edition Assessment Service Bulletin Number 1 History of the Stanford-Binet Intelligence Scales: Content and Psychometrics Kirk A. Becker The 2003 publication of the Stanford-Binet Intelligence Scales, Fifth Edition represents the latest in a series of innovations in the assessment of intelligence and abilities. Using qualitative and quantitative methods, this bulletin examines the similarities and differences between the different editions of the Stanford-Binet published over the past century. It discusses the development and integration of age-scale and point-scale formats for subtests, the theoretical structure of the test (single versus hierarchical, use of Nonverbal and Verbal domains, and links to the Cattell-Horn-Carroll theory), and changes in item content related to this theoretical structure. The new edition provides greater differentiation in the measurement of abilities, the precursors of which were nevertheless present in earlier editions.
