| dw testing concepts: Testing the Data Warehouse Practicum Wayne Yaddow Doug Vucevic &, 2012-08 The quality of a data warehouse (DWH) is the elusive aspect of it, not because it is hard to achieve [once we agree what it is], but because it is difficult to describe. We propose the notion that quality is not an attribute or a feature that a product has to possess, but rather a relationship between that product and each and every stakeholder. More specifically, the relationship between the software quality and the organization that produces the products is explored. Quality of data that populates the DWH is the main concern of the book, therefore we propose a definition for data quality as: fitness to serve each and every purpose. Methods are proposed throughout the book to help readers achieve data warehouse quality. |

| dw testing concepts: Permutation Tests Phillip Good, 2013-03-09 Permutation tests permit us to choose the test statistic best suited to the task at hand. This freedom of choice opens up a thousand practical applications, including many which are beyond the reach of conventional parametric sta tistics. Flexible, robust in the face of missing data and violations of assump tions, the permutation test is among the most powerful of statistical proce dures. Through sample size reduction, permutation tests can reduce the costs of experiments and surveys. This text on the application of permutation tests in biology, medicine, science, and engineering may be used as a step-by-step self-guiding reference manual by research workers and as an intermediate text for undergraduates and graduates in statistics and the applied sciences with a first course in statistics and probability under their belts. Research workers in the applied sciences are advised to read through Chapters 1 and 2 once quickly before proceeding to Chapters 3 through 8 which cover the principal applications they are likely to encounter in practice. Chapter 9 is a must for the practitioner, with advice for coping with real life emergencies such as missing or censored data, after-the-fact covariates, and outliers. Chapter 10 uses practical applications in archeology, biology, climatology, education and social science to show the research worker how to develop new permutation statistics to meet the needs of specific applications. The practitioner will find Chapter 10 a source of inspiration as well as a practical guide to the development of new and novel statistics. |

| dw testing concepts: Concepts of Personality Joseph M. Wepman, 2017-07-12 The psychologist who pursues an interest in personality is constantly faced by a dilemma. He seeks to investigate what is to him the most intriguing and interesting subject--the multifaceted operations of man in his natural environment. The predicament lies in the discrepancy between the complexity and richness of man's subjective experience, and the pallid analog of these experiences the psychologist is able to study effectively with the research procedures available to him. In Concepts of Personality Joseph M. Wepman and Ralph W. Heine offer a comprehensive survey of classical and contemporary personality theory, including a wide array of examples of these two trends. If the psychologist holds to the premises of strict objectivity through controlled observations, he finds himself driven to the periphery of the very problem he seeks to understand. This is a place where the reliability of measurement and the validity and predictability of his instruments can often be specified, but only at the cost of abandoning the goal of useful generality or of application to the individual in his ordinary life circumstances. Concepts of Personality, unlike most books on the subject, is not limited to broad, general theories. It includes chapters on basic processes--learning, perception, genetics, and drive theory; on the major analytical approaches of psychology and psychiatry; on anthropological and sociological contributions; and on the problems of measurement and assessment. Each chapter is by an authority on the point of view expressed. The editors' introduction, itself a major essay on the complex and divergent patterns and themes of contemporary views of personality, carefully leads the reader through the information at hand. The book as a whole constitutes an encyclopedic summary of the state of the science. |

| dw testing concepts: Filtering the Web to Feed Data Warehouses Witold Abramowicz, Pawel J. Kalczynski, Krzysztof Węcel, 2002-07-24 Information is a key factor in business today, and data warehousing has become a major activity in the development and management of information systems to support the proper flow of information. Unfortunately, the majority of information systems are based on structured information stored in organizational databases, which means that the company is isolated from the business environment by concentrating on their internal data sources only. It is therefore vital that organizations take advantage of external business information, which can be retrieved from Internet services and mechanically organized within the existing information structures. Such a continuously extending integrated collection of documents and data could facilitate decision-making processes in the organization. Filtering the Web to Feed Data Warehouses discusses areas such as: - how to use data warehouse for filtering Web content - how to retrieve relevant information from diverse sources on the Web - how to handle the time aspect - how to mechanically establish links among data warehouse structures and documents filtered from external sources - how to use collected information to increase corporate knowledge and gives a comprehensive example, illustrating the idea of supplying data warehouses with relevant information filtered from the Web. |

| dw testing concepts: Open Source ETL-The Prodigy Kids Binayaka Mishra, 2017-06-19 It’s said, ETL concept gained popularity in the 1970s when organizations began using multiple data repositories, or databases, to store different types of business information but only as a technical concept. The need to integrate data that was spread across these databases grew quickly. ETL became the standard method for taking data from disparate sources and transforming it before loading it to a target source, or destination. In the late 1980s and early 1990s, data warehouses came onto the scene. A distinct type of database, data warehouses provided integrated access to data from multiple systems – mainframe computers, minicomputers, personal computers and spreadsheets. Coupled with mergers and acquisitions, many organizations wound up with several different ETL solutions that were not integrated. |

| dw testing concepts: A Compendium of Neuropsychological Tests Esther Strauss, Elisabeth M. S. Sherman, Otfried Spreen, 2006-04-06 For the practicing neuropsychologist or researcher, keeping up with the sheer number of newly published or updated tests is a challenge, as is evaluating the utility and psychometric properties of neuropsychological tests in a clinical context. The goal of the third edition of A Compendium of Neuropsychological Tests, a well-established neuropsychology reference text, is twofold. First, the Compendium is intended to serve as a guidebook that provides a comprehensive overview of the essential aspects of neuropsychological assessment practice. Second, it is intended as a comprehensive sourcebook of critical reviews of major neuropsychological assessment tools for the use by practicing clinicians and researchers. Written in a comprehensive, easy-to-read reference format, and based on exhaustive review of research literature in neuropsychology, neurology, psychology, and related disciplines, the book covers topics such as basic aspects of neuropsychological assessment as well as the theoretical background, norms, and the utility, reliability, and validity of neuropsychological tests. For this third edition, all chapters have been extensively revised and updated. The text has been considerably expanded to provide a comprehensive yet practical overview of the state of the field. Two new chapters have been added: Psychometrics in Neuropsychological Assessment and Norms in Psychological Assessment. The first two chapters present basic psychometric concepts and principles. Chapters three and four consider practical aspects of the history-taking interview and the assessment process itself. Chapter five provides guidelines on report-writing and chapters six through sixteen consist of detailed, critical reviews of neuropsychological tests, and address the topics of intelligence, achievement, executive function, attention, memory, language, visual perception, somatosensory olfactory function, mood/personality, and response bias. A unique feature is the inclusion of tables that summarize salient features of tests within each domain so that readers can easily compare measures. Additional tables within each test review summarize important features of each test, highlight aspects of each normative dataset, and provide an overview of psychometric properties. Of interest to neuropsychologists, neurologists, psychiatrists, and educational and clinical psychologists working with adults as well as pediatric populations, this volume will aid practitioners in selecting appropriate testing measures for their patients, and will provide them with the knowledge needed to make empirically supported interpretations of test results. |

The final section discusses topics of special relevance such as multi-trait multi-state analyses and development of screening instruments. |
| dw testing concepts: The Concept of Validity Robert W. Lissitz, 2009-11-01 Validity is widely held to be the most important criterion for an assessment. Nevertheless, assessment professionals have disagreed about the meaning of validity almost from the introduction of the term as applied to testing about 100 years ago. Over the years, the best and brightest people in assessment have contributed their thinking to this problem and the fact that they have not agreed is testimony to the complexity and importance of validity. Even today, ways to define validity are being debated in the published literature in the assessment profession. How can such a fundamental concept be so controversial? This book brings focus to diverse perspectives about validity. Its chapter authors were chosen because of their expertise and because they differ from each other in the ways they think about the validity construct. Its introduction and ten chapters bridge both the theoretical and the practical. Contributors include most prominent names in the field of validity and their perspectives are at once cogent and controversial. From these diverse and well-informed discussions, the reader will gain a deep understanding of the core issues in validity along with directions toward possible resolutions. The debate that exists among these authors is a rich one that will stimulate the reader’s own understanding and opinion. Several chapters are oriented more practically. Ways to study validity are presented by professionals who blend current assessment practice with new suggestions for what sort of evidence to develop and how to generate the needed information. In addition they provide examples of some of the options on how to present the validity argument in the most effective ways. The initial chapter by the Editor is an effort to orient the reader as well as providing an overview of the book. Bob Lissitz has provided a brief perspective on each of the subsequent chapters as well as presenting a series of questions regarding validation that the reader will want to try to answer for themselves, as he or she reads through this book. This book’s topic is fundamental to assessment, its authors are distinguished, and its scope is broad. It deserves to become established as a fundamental reference on validity for years to come. |

| dw testing concepts: Empirical Analysis of Entrepreneurship and Economic Growth André van Stel, 2006-06-15 The importance of entrepreneurship for achieving economic growth in contemporary economies is widely recognized, both by policy makers and economists. It is deeply embedded in the current European policy approach that the creativity and independence of entrepreneurs contribute to higher levels of economic activity. Indeed, according to the European Commission (2003, p. 9), The challenge for the European Union is to identify the key factors for building a climate in which entrepreneurial initiative and business activities can thrive. Policy measures should seek to boost the Union's levels of entrepreneurship, adopting the most appropriate approach for producing more entrepreneurs and for getting more firms to grow. Audretsch (2003, p. 5) states that Entrepreneurship has become the engine of economic and social development throughout the world. The relation between entrepreneurship and economic growth is embedded in several strands of the economic literature. A first strand of literature involves the general understanding of the role of entrepreneurship in the modern economy. Seminal contributions were made by Schumpeter (1934), Knight (1921) and Kirzner (1973). These economists stress different aspects of the role of the entrepreneur. While Schumpeter stresses the innovating aspect, Knight stresses the risk assuming aspect. Kirzner, finally, stresses the role of the entrepreneur in leading markets to equilibrium. Acs (1992) discusses the contribution of small firms in modern economies. |
| dw testing concepts: The Organisation of Conceptual Knowledge in the Brain Alex Martin, Alfonso Caramazza, 2003 Category-specific knowledge disorders are among the most intriguing and perplexing syndromes in cognitive neuropsychology. The past decade has witnessed increased interest in these disorders, due largely to a heightened appreciation of the profound implications that an understanding of concept representation has for such diverse topics as object recognition, the organisation of the lexicon, and storage of long-term memories. Until recently, information about the representation of concepts was limited to findings from patients with brain injury and disease. This state of affairs has now changed with the advent and wide-spread availability of functional imaging for studying cognition in the normal human brain. The purpose of this special issue is to provide a forum for new findings and critical, theoretical analyses of existing data from patient and functional brain imaging studies. The contributions, all from major investigators in the field, range from studies of specific object categories such as animals, tools, fruit and vegetables, and faces, to the more general domains of number processing, social interaction, and mechanical knowledge. A unifying theme of these papers is the extent to which the findings can be best understood within the context of models that posit an innate, domain-specific organisation, those that appeal to an organisation by sensory- and motor-based features and properties, and those that propose an undifferentiated, distributed neural organisation. |

Bourne, 2014-06-28 Food Science and Technology: A Series of Monographs: Food Texture and Viscosity: Concept and Measurement focuses on the texture and viscosity of food and how these properties are measured. The publication first elaborates on texture, viscosity, and food, body-texture interactions, and principles of objective texture measurement. Topics include area and volume measuring instruments, chemical analysis, multiple variable instruments, soothing effect of mastication, reasons for masticating food, rheology and texture, and the rate of compression between the teeth. The book then examines the practice of objective texture measurement and viscosity and consistency, including the general equation for viscosity, methods for measuring viscosity, factors affecting viscosity, tensile testers, distance measuring measurements, and shear testing. The manuscript takes a look at the selection of a suitable test procedure and sensory methods of texture and viscosity measurement. Discussions focus on nonoral methods of sensory measurement; correlations between subjective and objective measurements; variations on the texture profile technique; and importance of sensory evaluation. The publication is a vital source of information for food experts and researchers interested in food texture and viscosity. |
