This book was released on 1961 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes an application of a hierarchical grouping procedure to a problem of grouping test profiles to maximize the homogeneity of profiles within the same clusters, taking account of all profile variables and all clusters at the same time. The data are 25 test profiles to which Sawrey, Keller, + Conger applied a different grouping technique. The results of the two grouping techniques are compared. Desirable characteristics of the hierarchical grouping technique are demonstrated.Any measure of profile similarity can be used. It is unnecessary to specify in advance the number of groups to be formed or to select nucleus groups. The cost of grouping can be evaluated in terms of any criterion expressed as a functional relation, or objective function. The resulting hierarchical structure of k profiles is that which, at each stage (k, k-1, ..., 1), least impairs the objective-function value. hus the hierarchical grouping technique shows not only the order in which profiles must be grouped so as to yield the optimal value of the objective function when the number of profiles is systematically reduced, but also the costs of the grouping at each stage of the hierarchy.

Download or read book Population Growth and Urban Systems Development written by G.A. van der Knapp and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of the evolution of an urban system raises a number of practical questions, as to the operational definition of the components of the system as well as to the incorporation of the factor time in the analysis. In this chapter the fo cuss is on the urban centres, the nodes of the urban system. One of the first pro blems to be solved now is the definition of such a node. It has been argued above that population size can be used as an approximation of the complexity of the spatial economic structure of a region. The acceptation of this notion makes it possible to study the urban system as a population system. The analysis of the population system over the study period will be pursued from this perspective. The study period, 1840-1970, covers completely the industrialization and urbanization phase which occurred during the industrial revolution. Over this period the spatial organizational structure of society evolved from a rural-commercial to wards a modern urban-industrial state. One of the major events in this period of change is the spatial redistribution of the population and the population growth. This process will be examined below at three levels of aggregation: (I) the popu lation distribution as one frequency distribution, (2) the population distribution dis aggregated into a n~ber of size classes, and (3) the individual cities which make up the population distribution.

Download or read book Cluster Analysis written by B. S. Duran and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: A tremendous amount of work has been done over the last thirty years in cluster analysis, with a significant amount occurring since 1960. A substantial portion of this work has appeared in many journals, including numerous applied journals, and a unified ex position is lacking. The purpose of this monograph is to supply such an exposition by presenting a brief survey on cluster analysis. The main intent of the monograph is to give the reader a quick account of the prob lem of cluster analysis and to expose to him the various aspects thereof. With this intent in mind much detail has been omitted, particularly in so far as detailed examples are considered. Most of the references stated within the text contain examples and the reader can consult them for additional information on specific topics. Efforts were made to include in the reference section all papers that played a role in developing the "theory" of cluster analysis. Any omission of such references was not intentional and we would appreciate knowing about them. Many references to papers in applied journals are also contained, however, the list-is far from being complete. This monograph has been greatly influenced by the work of many people, most notably, J. A. Hartigan, D. Wishart, J. K. Bryan, R. E. Jensen, H. D. Vinod, and M. R. Rao. Several portions of the monograph were motivated by research performed under the support of NASA Manned Spacecraft Center, Earth Observations Division, under Contract NAS 9-12775.

Download or read book Military Personnel Measurement written by Martin F. Wiskoff and published by Praeger. This book was released on 1989-08-07 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume documents military advances in personnel measurement technology and practices. The military is the unquestionable forerunner of this technology. Until now some of this knowledge has not been easily accessible to the scientific community at large. This book highlights advances in enlisted personnel screening and selection from World War I to the present. It foresees the future era of testing, through the use of Item Response Theory, computerized adaptive testing, and the development of new computerized tests. The contributors study the use of computer systems to address person-job match and vocational guidance. They also describe selection to various officer candidate programs and examine the criteria of enlisted performance during peacetime. Military Personnel Measurement covers the full scope of military personnel technology and includes discussions of current topics including: computerized vocational guidance systems; advances in vocational testing; personnel classification; evaluations of enlisted performance. Students and professionals in the areas of personnel management, business administration, military studies, or anyone interested in the use of new technology in the testing and evaluation of personnel, will find Military Personnel Measurement a valuable resource.

Available in PDF, EPUB and Kindle. Book excerpt: Like most academic authors, my views are a joint product of my teaching and my research. Needless to say, my views reflect the biases that I have acquired. One way to articulate the rationale (and limitations) of my biases is through the preface of a truly great text of a previous era, Cooley and Lohnes (1971, p. v). They draw a distinction between mathematical statisticians whose intel lect gave birth to the field of multivariate analysis, such as Hotelling, Bartlett, and Wilks, and those who chose to "concentrate much of their attention on methods of analyzing data in the sciences and of interpreting the results of statistical analysis . . . . (and) . . . who are more interested in the sciences than in mathematics, among other characteristics. " I find the distinction between individuals who are temperamentally "mathe maticians" (whom philosophy students might call "Platonists") and "scientists" ("Aristotelians") useful as long as it is not pushed to the point where one assumes "mathematicians" completely disdain data and "scientists" are never interested in contributing to the mathematical foundations of their discipline. I certainly feel more comfortable attempting to contribute in the "scientist" rather than the "mathematician" role. As a consequence, this book is primarily written for individuals concerned with data analysis. However, as noted in Chapter 1, true expertise demands familiarity with both traditions.

Download or read book Handbook of Quantitative Methods for Educational Research written by Timothy Teo and published by Springer Science & Business Media. This book was released on 2014-02-07 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of their research activities, researchers in all areas of education develop measuring instruments, design and conduct experiments and surveys, and analyze data resulting from these activities. Educational research has a strong tradition of employing state-of-the-art statistical and psychometric (psychological measurement) techniques. Commonly referred to as quantitative methods, these techniques cover a range of statistical tests and tools. Quantitative research is essentially about collecting numerical data to explain a particular phenomenon of interest. Over the years, many methods and models have been developed to address the increasingly complex issues that educational researchers seek to address. This handbook serves to act as a reference for educational researchers and practitioners who desire to acquire knowledge and skills in quantitative methods for data analysis or to obtain deeper insights from published works. Written by experienced researchers and educators, each chapter in this handbook covers a methodological topic with attention paid to the theory, procedures, and the challenges on the use of that particular methodology. It is hoped that readers will come away from each chapter with a greater understanding of the methodology being addressed as well as an understanding of the directions for future developments within that methodological area.
