Designed to assist those working in health research, An Introduction to Stata for Health Researchers, explains how to maximize the versatile Strata program for data management, statistical analysis, and graphics for research. The first nine chapters are devoted to becoming familiar with Stata and the essentials of effective data management. The text is also a valuable companion reference for more advanced users. It covers a host of useful applications for health researchers including the analysis of stratified data via epitab and regression models; linear, logistic, and Poisson regression; survival analysis including Cox regression, standardized rates, and correlation/ROC analysis of measurements.

?konometrie; nicht nur der Begriff ist etwas sperrig, auch die Inhalte erschlie?en sich nicht jedem sofort. Wichtig und interessant ist sie aber trotzdem. Roberto Pedace erkl?rt Ihnen, worum es in der ?konometrie geht, wie Sie Test-Hypothesen aufstellen und vieles mehr. Er erl?utert, wie Sie mit Regressionsmodellen arbeiten und mit diskreten und abh?ngigen Variablen umgehen. Gegen Ende des Buches geht er ?ber die Basismodelle hinaus und f?hrt Sie in statische und dynamische Modelle sowie die Kunst der Vorhersagen ein.

Computer-Aided Multivariate Analysis, Fourth Edition enables researchers and students with limited mathematical backgrounds to understand the concepts underlying multivariate statistical analysis, perform analysis using statistical packages, and understand the output. New topics include Loess and Poisson regression, nominal and ordinal logistic regression, interpretation of interactions in logistic and survival analysis, and imputation for missing values. This book includes new exercises and references, and updated options in the latest versions of the statistical packages. All data sets and codebooks are available for download. The authors explain the assumptions made in performing each analysis and test, how to determine if your data meets those assumptions, and what to do if they do not. What to Watch out for sections in each chapter warn of common difficulties. By reading this text, you will know what method to use with your data set, how to get the results, and how to interpret them and explain them to others. New in the Fourth Edition: Expanded explanation of checking for goodness of fit in logistic regression and survival analysis Kaplan-Meier estimates of survival curves, formal tests for comparing survival between groups, interactions and the use of time-dependent covariates in survival analysis Expanded discussion of how to handle missing values Latest features of the S-PLUS package in addition to SAS, SPSS, STATA, and STATISTICA for multivariate analysis Data sets for the problems are available at the CRC web site: http://www.crcpress.com/product/isbn/9781584883081 Commands and output for examples used in the text for each statistical package are available at the UCLA web site: http://www.ats.ucla.edu/stat/examples/cama4/

Mathematik in den Wirtschaftswissenschaften bedeutet einerseits das Problem, mathematische Ideen zu verstehen, um die dazugehörigen Techniken zu beherrschen und andererseits, diese zunächst abstrakten Techniken zielgerichtet und sinnvoll für ökonomische Anwendungen nutzbar zu machen. Das nun in der 17. Auflage vorliegende Buch ist als Lehr-, Arbeits- und Übungsbuch vorrangig zum Selbststudium konzipiert. Es berücksichtigt beide Aspekte durch ausführliche Darstellung, Begründung und Einübung mathematischer Grundelemente und ökonomisch relevanter mathematischer Techniken. Die aktuelle Auflage enthält erstmals einen Intensiv-Brückenkurs zur elementaren Algebra mit mehr als 500 Übungselementen (in Übungsaufgaben, Selbstkontroll-Tests, Eingangstest, Schlusstest).

New Edition of a Classic Guide to Statistical Applications in the Biomedical Sciences In the last decade, there have been significant changes in the way statistics is incorporated into biostatistical, medical, and public health research. Addressing the need for a modernized treatment of these statistical applications, Basic Statistics, Fourth Edition presents relevant, up-to-date coverage of research methodology using careful explanations of basic statistics and how they are used to address practical problems that arise in the medical and public health settings. Through concise and easy-to-follow presentations, readers will learn to interpret and examine data by applying common statistical tools, such as sampling, random assignment, and survival analysis. Continuing the tradition of its predecessor, this new edition outlines a thorough discussion of different kinds of studies and guides readers through the important, related decision-making processes such as determining what information is needed and planning the collections process. The book equips readers with the knowledge to carry out these practices by explaining the various types of studies that are commonly conducted in the fields of medical and public health, and how the level of evidence varies depending on the area of research. Data screening and data entry into statistical programs is explained and accompanied by illustrations of statistical analyses and graphs. Additional features of the Fourth Edition include: A new chapter on data collection that outlines the initial steps in planning biomedical and public health studies A new chapter on nonparametric statistics that includes a discussion and application of the Sign test, the Wilcoxon Signed Rank test, and the Wilcoxon Rank Sum test and its relationship to the Mann-Whitney U test An updated introduction to survival analysis that includes the Kaplan Meier method for graphing the survival function and a brief introduction to tests for comparing survival functions Incorporation of modern statistical software, such as SAS, Stata, SPSS, and Minitab into the presented discussion of data analysis Updated references at the end of each chapter Basic Statistics, Fourth Edition is an ideal book for courses on biostatistics, medicine, and public health at the upper-undergraduate and graduate levels. It is also appropriate as a reference for researchers and practitioners who would like to refresh their fundamental understanding of statistical techniques.

Der Weiblichkeitswahn oder Die Selbstbefreiung der Frau

Ein Emanzipationskonzept

Author: Betty Friedan

Publisher: Rowohlt Verlag GmbH

ISBN: 3688100425

Category: Social Science

Page: 282

Der Titel dieses heftig umstrittenen Bestsellers ist in die Umgangssprache eingegangen. Weiblichkeitswahn – das ist die von mächtigen wirtschaftlichen Interessengruppen manipulierte Umkehrung der Frauenemanzipation. Die Frau wird durch psychologische Dauerbeeinflussung in der Werbung und in den Massenmedien zur «glücklichen Hausfrau und Mutter» umfunktioniert, wird als kaufkräftige Konsumentin umschmeichelt und auf ein Sexualsymbol mit Warencharakter reduziert. Betty Friedan führt ein erdrückendes Beweismaterial ins Feld gegen das entstellte Image des weiblichen Wesens in unserer Zivilisation. Die Autorin zeigt allerdings auch Wege, auf denen die moderne Frau trotz aller Widerstände ihren eigenen Glücksansprüchen und denen der Familie gerecht werden kann. Dieses Werk einer intelligenten und temperamentvollen Frau über die Frau sollte auch Pflichtlektüre für Männer sein.

Multilevel and Longitudinal Modeling Using Stata, Second Edition

This is a book about applied multilevel and longitudinal modeling. Other terms for multilevel models include hierarchical models, random-effects or random-coefficient models, mixed-effects models, or simply mixed models. Longitudinal data are also referred to as panel data, repeated measures, or cross-sectional time series. A popular type of multilevel model for longitudinal data is the growth-curve model. Our emphasis is on explaining the models and their assumptions, applying the methods to real data, and interpreting results.
