Missing data have long plagued those conducting applied research in the social, behavioral, and health sciences. Good missing data analysis solutions are available, but practical information about implementation of these solutions has been lacking. The objective of Missing Data: Analysis and Design is to enable investigators who are non-statisticians to implement modern missing data procedures properly in their research, and reap the benefits in terms of improved accuracy and statistical power. Missing Data: Analysis and Design contains essential information for both beginners and advanced r

"Panel Data Analysis using EViews provides graduate students, researchers, and statisticians with step-by-step guidance on how to apply EViews software to panel data analysis using appropriate empirical models and real datasets. The author explores a variety of panel data models, along with the authors own empirical findings, demonstrating the advantages and limitations of each model. The text also examines various alternative models based on panel data, as well as the best and worst ANCOVA models"--

In der Entscheidungsphase für ein CAQDAS-Programm ("Computer Assisted Qualitative Data Analysis Software") im Rahmen meines Forschungsprojektes über die Bedeutung von Kultur und Religion für die Menschenrechte von Frauen in Malaysia habe ich mir zum einen Gedanken über die Dominanz der gegenstandsbezogenen Theoriebildung (Grounded Theory) und zum anderen über die Dominanz des Kodierens als Methode gemacht. Im ersten Teil des Aufsatzes diskutiere ich, inwieweit meine Forschung auf den Prinzipien und Praktiken der Grounded Theory (GT) aufbaut bzw. aufgrund meines hypothesengeleiteten Rahmenkonzepts und der Auswahlkriterien für Untersuchungsteilnehmer(innen) davon abweicht. Ich zeige, in welcher Weise die Anwendung der GT zur Verbesserung des qualitativen Forschungsprozesses im Rahmen meiner Arbeit beigetragen hat. Dabei ist ein Ziel, den paradigmatischen Status der GT im Zusammenhang mit CAQDAS und die damit verbundene Homogenisierung zu entmystifizieren. Im zweiten Teil des Aufsatzes wird die Problematik des Kodierens als Analysemethode behandelt, und es wird gezeigt, wie diese mittels Reflexivität und "Agency" (Selbstbestimmung) des Forschers/der Forscherin bewältigt werden kann. Hierbei stehen eine pragmatische Herangehensweise und die Anwendung von Kodes als Mittel zum Zweck – und nicht als eigentliches Ziel – im Vordergrund. Abschließend wird die Frage erörtert, ob CAQDAS die Güte der qualitativen Datenanalyse und die Transparenz der Methode erhöht, (z.B. durch die Verwendung eines Audittrails) und somit zu einer nachvollziehbaren, innovativen und effektiven Forschung beiträgt.

Students of politics use statistical and quantitative techniques to: summarize a large body of numbers into a small collection of typical values;confirm (and perhaps sanctify) the results of the analysis by using tests of statistical significance that help protect against sampling and measurement error;discover what's going on in their data and expose some new relationships; andinform their audience what's going on in the data.

The topic of quality management is so expansive that it raises the issue of how to teach the subject in a way that students find engaging, meaningful, and useful. The Personal Data Analysis Exercise is designed to achieve these objectives by having students apply the quality management process to their everyday lives. In the exercise, students develop valued self-improvement goals that can be accomplished within the semester. They take actions to achieve the goals, collect data to monitor their progress, identify "defects" in their behaviors, and analyze their behaviors using quality tools to find new ways to eliminate the defects and accomplish the goals. The article explains the exercise and includes a teaching guide and instructional aids.
