Now in its second edition, this textbook provides an applied and unified introduction to parametric, nonparametric and semiparametric regression that closes the gap between theory and application. The most important models and methods in regression are presented on a solid formal basis, and their appropriate application is shown through numerous examples and case studies. The most important definitions and statements are concisely summarized in boxes, and the underlying data sets and code are available online on the book’s dedicated website. Availability of (user-friendly) software has been a major criterion for the methods selected and presented.The chapters address the classical linear model and its extensions, generalized linear models, categorical regression models, mixed models, nonparametric regression, structured additive regression, quantile regression and distributional regression models. Two appendices describe the required matrix algebra, as well as elements of probability calculus and statistical inference.In this substantially revised and updated new edition the overview on regression models has been extended, and now includes the relation between regression models and machine learning, additional details on statistical inference in structured additive regression models have been added and a completely reworked chapter augments the presentation of quantile regression with a comprehensive introduction to distributional regression models. Regularization approaches are now more extensively discussed in most chapters of the book.The book primarily targets an audience that includes students, teachers and practitioners in social, economic, and life sciences, as well as students and teachers in statistics programs, and mathematicians and computer scientists with interests in statistical modeling and data analysis. It is written at an intermediate mathematical level and assumes only knowledge of basic probability, calculus, matrix algebra and statistics.

Eine medizinische Doktorarbeit zu schreiben, ist kein Spaziergang - eher eine Bergwanderung. Vorbereitung und Planung sind daher genauso wichtig wie eine detaillierte Karte, die den direkten Weg zum Gipfel weist. Dieses Buch ist eine solche Karte, denn es gliedert den Schreibprozess in Etappen, die die Promovierenden erfolgreich absolvieren k nnen - Schritt f r Schritt. Dieses Buch ist eine praktische Schreibanleitung. Mit seinen vielen Praxis-Tipps und Formulierungshilfen eignet es sich als Hands-On-Anleitung, die sich Promovierende direkt neben ihre Tastatur legen k nnen. Und: Dieses Buch hat System. Es beschreibt ein strukturiertes Vorgehen, das in definierten Schreibphasen zu einer Doktorarbeit f hrt, die alle wissenschaftlichen, stilistischen und formalen Anforderungen erf llt.

Since the end of WWII, not only the number of international regimes and organizations, but also the number of regional organisations and groups increased considerably. Today, states are often members of regional and international organisations at the same time and cover similar policies in both. This contributes to a regionalization of international relations since not only states, but also regional actors are active in international negotiations. This book provides a comprehensive analysis of how active and how influential regional actors are in today’s international negotiations. Based on a quantitative analysis of more than 500 international negotiations and three in-depth case studies, the book not only explains why some regional actors are more vocal than others in international organisations, but also why they differ concerning their prospects for success.
