Available in PDF, EPUB and Kindle. Book excerpt: This Ph.D. thesis concerns the problem of assessing distributional properties in multivariate regression models with possibly related marginal models. Such models are of great importance in most branches of statistics. The four papers in this thesis deal with different distributional aspects of relevance for all models. Paper 1 concerns the problem of assessing normality in the multivariate regression model. Paper 2 concerns the problem of assessing normality in situations when the data is heteroscedastic or autocorrelated. Paper 3 concerns testing for heteroscedasticity in linear regression models. Paper 4 presents four different types of tests for autocorrelation to be used in SUR models or multivariate regressions.

Book Synopsis Statistical Surveillance by : David Bock
Download or read book Statistical Surveillance written by David Bock and published by . This book was released on 2004 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a Ph.D. dissertation. Statistical surveillance is used to repeatedly evaluate the amount of information contained in observations which are achieved continuously. This makes it possible to quickly and safely detect changes in the way economic and financial time series evolve through time. Thus, the optimal time for decisions can be determined. The thesis treats systems for early warnings of turns in economic processes. In papers I & II it is demonstrated how such systems can be used to predict the turning points of the general business cycle, by detecting turns in leading indicators. In papers III & IV some strategies for timely transactions in the financial market are analyzed by means of the theory of statistical surveillance.

Book Synopsis Quick Ethnography by : Penn W. Handwerker
Download or read book Quick Ethnography written by Penn W. Handwerker and published by Rowman Altamira. This book was released on 2001-11-27 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quick Ethnography (QE) is an easy-to-read guide to the rapid collection of high quality ethnographic data for use in research, policy analysis, and decision-making. It addresses the needs of social scientists grappling with complex cultural social interactions and cultural change occurring in communities around the globe by offering a comprehensive, integrated multi-method approach that will increase research productivity. Handwerker provides step-by-step procedures for producing lots of data very quickly, outlining how ethnographers must control field preparation, data collection, and methods of data analysis. The rigorous QE approach allows greater precision and subtlety of ethnographic description and explanation that is not always possible in applied contract work (known as Rapid Assessment Procedures). The author, an anthropologist who has been teaching and consulting on fieldwork methods for over 25 years, includes extensive examples of research design and management that are valuable for the novice as well as for experienced researchers in all social science disciplines.

Book Synopsis Multi-parameter Mueller Matrix Microscopy for the Expert Assessment of Acute Myocardium Ischemia by : Victor Bachinsky
Download or read book Multi-parameter Mueller Matrix Microscopy for the Expert Assessment of Acute Myocardium Ischemia written by Victor Bachinsky and published by Springer Nature. This book was released on 2021-04-13 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an essential overview of the basic principles of imaging modalities, accompanied by examples of their applications in modern clinical and associated pre-clinical studies. The monograph is based on the original results of investigation of the efficiency use of laser light and Mueller-matrix polarimetry approach for assessment of myocardial tissues towards confirmation the cause of death. A morphological analysis of necrotic changes in the myocardial tissue of patients that died due to heart attack, coronary heart disease and acute coronary insufficiency was carried out and the data and histological sections of the myocardium inspected utilizing Mueller-matrix mapping of tissue samples with polarized light. A unified optical model of polycrystalline structure of the myocardium is proposed, and the principles and regulations of Mueller-matrix description of its polarization manifestations are explored and developed. The book also provides a statistical and scale-selective wavelet analysis of polarization and Mueller-matrix maps. Finally, the key forensic medical criteria for the differential diagnosis of the cause of death due to necrotic and pathological changes in the morphological structure of the myocardium have been established

Book Synopsis A Multidimensional Economic Assessment of Africa by : Jacob Wood
Download or read book A Multidimensional Economic Assessment of Africa written by Jacob Wood and published by Springer Nature. This book was released on 2020-05-27 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a useful resource for government policy analysts, academics, students of higher education and business practitioners interested in African economies and the key economic issues these economies are facing in 2020. In the face of weak governance and growth globally, there is still a window of opportunity for countries in Africa to build on not only their traditional industrial capabilities, but also pave the way for positive developments in international trade and in the way governments tackle poverty and inequality. By focusing on four areas: (1) agriculture and livestock, (2) consumption, poverty and inequality, (3) financial services, employment and corporate governance, and (4) economic integration, international trade and foreign direct investment (FDI), this book presents a series of empirical studies that examine important contemporary economic issues facing Africa. The book incorporates a range of methodological approaches, with some chapters providing case study analyses while others embrace more traditional forms of econometric testing.
Book Synopsis Flood Risk Assessment and Management by : Andreas H. Schumann
Download or read book Flood Risk Assessment and Management written by Andreas H. Schumann and published by Springer Science & Business Media. This book was released on 2011-01-04 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flood catastrophes which happened world-wide have shown that it is not sufficient to characterize the hazard caused by the natural phenomenon "flood" with the well-known 3M-approach (measuring, mapping and modelling). Due to the recent shift in paradigms from a safety oriented approach to risk based planning it became necessary to consider the harmful impacts of hazards. The planning tasks changed from attempts to minimise hazards towards interventions to reduce exposure or susceptibility and nowadays to enhance the capacities to increase resilience. Scientific interest shifts more and more towards interdisciplinary approaches, which are needed to avoid disaster. This book deals with many aspects of flood risk management in a comprehensive way. As risks depend on hazard and vulnerabilities, not only geophysical tools for flood forecasting and planning are presented, but also socio-economic problems of flood management are discussed. Starting with precipitation and meteorological tools to its forecasting, hydrological models are described in their applications for operational flood forecasts, considering model uncertainties and their interactions with hydraulic and groundwater models. With regard to flood risk planning, regionalization aspects and the options to utilize historic floods are discussed. New hydrological tools for flood risk assessments for dams and reservoirs are presented. Problems and options to quantify socio-economic risks and how to consider them in multi-criteria assessments of flood risk planning are discussed. This book contributes to the contemporary efforts to reduce flood risk at the European scale. Using many real-world examples, it is useful for scientists and practitioners at different levels and with different interests.

Book Synopsis Safety and performance concept. Reliability assessment of concrete structures by : fib Fédération internationale du béton
Download or read book Safety and performance concept. Reliability assessment of concrete structures written by fib Fédération internationale du béton and published by FIB - Féd. Int. du Béton. This book was released on 2018-08-01 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concrete structures have been built for more than 100 years. At first, reinforced concrete was used for buildings and bridges, even for those with large spans. Lack of methods for structural analysis led to conservative and reliable design. Application of prestressed concrete started in the 40s and strongly developed in the 60s. The spans of bridges and other structures like halls, industrial structures, stands, etc. grew significantly larger. At that time, the knowledge of material behaviour, durability and overall structural performance was substantially less developed than it is today. In many countries statically determined systems with a fragile behavior were designed for cast in situ as well as precast structures. Lack of redundancy resulted in a low level of robustness in structural systems. In addition, the technical level of individual technologies (e.g. grouting of prestressed cables) was lower than it is today. The number of concrete structures, including prestressed ones, is extremely high. Over time and with increased loading, the necessity of maintaining safety and performance parameters is impossible without careful maintenance, smaller interventions, strengthening and even larger reconstructions. Although some claim that unsatisfactory structures should be replaced by new ones, it is often impossible, as authorities, in general, have only limited resources. Most structures have to remain in service, probably even longer than initially expected. In order to keep the existing concrete structures in an acceptable condition, the development of methods for monitoring, inspection and assessment, structural identification, nonlinear analysis, life cycle evaluation and safety and prediction of the future behaviour, etc. is necessary. The scatter of individual input parameters must be considered as a whole. This requires probabilistic approaches to individual partial problems and to the overall analysis. The members of the fib Task Group 2.8 “Safety and performance concepts” wrote, on the basis of the actual knowledge and experience, a comprehensive document that provides crucial knowledge for existing structures, which is also applicable to new structures. This guide to good practice is divided into 10 basic chapters dealing with individual issues that are critical for activities associated with preferably existing concrete structures. Bulletin 86 starts with the specification of the performance-based requirements during the entire lifecycle. The risk issues are described in chapter two. An extensive part is devoted to structural reliability, including practical engineering approaches and reliability assessment of existing structures. Safety concepts for design consider the lifetime of structures and summarise safety formats from simple partial safety factors to develop approaches suitable for application in sophisticated, probabilistic, non-linear analyses. Testing for design and the determination of design values from the tests is an extremely important issue. This is especially true for the evaluation of existing structures. Inspection and monitoring of existing structures are essential for maintenance, for the prediction of remaining service life and for the planning of interventions. Chapter nine presents probabilistically-based models for material degradation processes. Finally, case studies are presented in chapter ten. The results of the concrete structures monitoring as well as their application for assessment and prediction of their future behaviour are shown. The risk analysis of highway bridges was based on extensive monitoring and numerical evaluation programs. Case studies perfectly illustrate the application of the methods presented in the Bulletin. The information provided in this guide is very useful for practitioners and scientists. It provides the reader with general procedures, from the specification of requirements, monitoring, assessment to the prediction of the structures’ lifecycles. However, one must have a sufficiently large amount of experimental and other data (e.g. construction experience) in order to use these methods correctly. This data finally allows for a statistical evaluation. As it is shown in case studies, extensive monitoring programs are necessary. The publication of this guide and other documents developed within the fib will hopefully help convince the authorities responsible for safe and fluent traffic on bridges and other structures that the costs spent in monitoring are first rather small, and second, they will repay in the form of a serious assessment providing necessary information for decision about maintenance and future of important structures.

Book Synopsis Comparative Analysis Of Nations by : Robert Perry
Download or read book Comparative Analysis Of Nations written by Robert Perry and published by Routledge. This book was released on 2019-03-01 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: The comparative method is fundamental and critical for political scientists, and especially those interested in comparative politics. Such questions as how democratic is the United States, how rich is Germany, and how ethnically complex is Nigeria-and what effects these attributes have on important political phenomena-cannot be analyzed except comparatively. To understand politics we need to think in terms of concepts, processes, behavior and authority patterns that transcend specific regions or nation-states. Comparative Analysis of Nations is designed to address three questions confronting the study of politics: (1) What do I do once I have identified a question that I want to explore within a cross-national perspective? (2) How do I proceed so I adequately address this question? (3) Why should I proceed with this particular study plan? Perry and Robertson examine how to conceptualize, operationalize, measure, sample, analyze, and evaluate these research questions. In clear language they stress the logic behind basic techniques of quantitative analysis, issues of measurement and hypothesis testing, basic techniques of hypothesis testing (tabular analysis, ANOVA, scatterplots, bivariate regression) and advanced bivariate analysis (curvilinear and multiple regression). The book requires no previous training in statistics or math. Cross-national data sets accompany the book on a CD-ROM and are compatible with the popular SPSS package. The data sets enable the instructor the opportunity to engage the students directly in devising their own modified models of analysis to complement and extend the demonstrations within the text. In sum, the text integrates the core tools and strategies of social science analysis within a framework that highlights the quantitative study of comparative politics.

Book Synopsis Facets of Behaviormetrics by : Akinori Okada
Download or read book Facets of Behaviormetrics written by Akinori Okada and published by Springer Nature. This book was released on 2023-09-17 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited book is the first one written in English that deals comprehensively with behavior metrics. The term “behaviormetrics” comprehends the research including all sorts of quantitative approaches to disclose human behavior. Researchers in behavior metrics have developed, extended, and improved methods such as multivariate statistical analysis, survey methods, cluster analysis, machine learning, multidimensional scaling, corresponding analysis or quantification theory, network analysis, clustering, factor analysis, test theory, and related factors. In the spirit of behavior metrics, researchers applied these methods to data obtained by surveys, experiments, or websites from a diverse range of fields. The purpose of this book is twofold. One is to represent studies that display how the basic elements of behavior metrics have developed into present-day behavior metrics. The other is to represent studies performed mainly by those who would like to pioneer new fields of behavior metrics and studies that display elements of future behavior metrics. These studies consist of various characteristics such as those dealing with theoretical or conceptual subjects, the algorithm, the model, the method, and the application to a wide variety of fields. This book helps readers to understand the present and future of behavior metrics.
