Test Configurations, Stabilities and Canonical Kahler Metrics - Toshiki Mabuchi - Bog - Springer Verlag, Singapore - Plusbog.dk

Test Configurations, Stabilities and Canonical Kahler Metrics - Toshiki Mabuchi - Bog - Springer Verlag, Singapore - Plusbog.dk

The Yau-Tian-Donaldson conjecture for anti-canonical polarization was recently solved affirmatively by Chen-Donaldson-Sun and Tian. However, this conjecture is still open for general polarizations or more generally in extremal Kähler cases. In this book, the unsolved cases of the conjecture will be discussed. It will be shown that the problem is closely related to the geometry of moduli spaces of test configurations for polarized algebraic manifolds. Another important tool in our approach is the Chow norm introduced by Zhang. This is closely related to Ding''s functional, and plays a crucial role in our differential geometric study of stability. By discussing the Chow norm from various points of view, we shall make a systematic study of the existence problem of extremal Kähler metrics.

Diagnostic Methods in Time Series - Anna Clara Monti - Bog - Springer Verlag, Singapore - Plusbog.dk

Diagnostic Methods in Time Series - Anna Clara Monti - Bog - Springer Verlag, Singapore - Plusbog.dk

This book contains new aspects of model diagnostics in time series analysis, including variable selection problems and higher-order asymptotics of tests. This is the first book to cover systematic approaches and widely applicable results for nonstandard models including infinite variance processes. The book begins by introducing a unified view of a portmanteau-type test based on a likelihood ratio test, useful to test general parametric hypotheses inherent in statistical models. The conditions for the limit distribution of portmanteau-type tests to be asymptotically pivotal are given under general settings, and very clear implications for the relationships between the parameter of interest and the nuisance parameter are elucidated in terms of Fisher-information matrices. A robust testing procedure against heavy-tailed time series models is also constructed in the context of variable selection problems. The setting is very reasonable in the context of financial data analysis and econometrics, and the result is applicable to causality tests of heavy-tailed time series models. In the last two sections, Bartlett-type adjustments for a class of test statistics are discussed when the parameter of interest is on the boundary of the parameter space. A nonlinear adjustment procedure is proposed for a broad range of test statistics including the likelihood ratio, Wald and score statistics.

Asymptotic Statistical Inference - Shailaja Deshmukh - Bog - Springer Verlag, Singapore - Plusbog.dk

Asymptotic Statistical Inference - Shailaja Deshmukh - Bog - Springer Verlag, Singapore - Plusbog.dk

The book presents the fundamental concepts from asymptotic statistical inference theory, elaborating on some basic large sample optimality properties of estimators and some test procedures. The most desirable property of consistency of an estimator and its large sample distribution, with suitable normalization, are discussed, the focus being on the consistent and asymptotically normal (CAN) estimators. It is shown that for the probability models belonging to an exponential family and a Cramer family, the maximum likelihood estimators of the indexing parameters are CAN. The book describes some large sample test procedures, in particular, the most frequently used likelihood ratio test procedure. Various applications of the likelihood ratio test procedure are addressed, when the underlying probability model is a multinomial distribution. These include tests for the goodness of fit and tests for contingency tables. The book also discusses a score test and Wald''s test, their relationship with the likelihood ratio test and Karl Pearson''s chi-square test. An important finding is that, while testing any hypothesis about the parameters of a multinomial distribution, a score test statistic and Karl Pearson''s chi-square test statistic are identical. Numerous illustrative examples of differing difficulty level are incorporated to clarify the concepts. For better assimilation of the notions, various exercises are included in each chapter. Solutions to almost all the exercises are given in the last chapter, to motivate students towards solving these exercises and to enable digestion of the underlying concepts. The concepts from asymptotic inference are crucial in modern statistics, but are difficult to grasp in view of their abstract nature. To overcome this difficulty, keeping up with the recent trend of using R software for statistical computations, the book uses it extensively, for illustrating the concepts, verifying the properties of estimators and carrying out various test procedures. The last section of the chapters presents R codes to reveal and visually demonstrate the hidden aspects of different concepts and procedures. Augmenting the theory with R software is a novel and a unique feature of the book. The book is designed primarily to serve as a text book for a one semester introductory course in asymptotic statistical inference, in a post-graduate program, such as Statistics, Bio-statistics or Econometrics. It will also provide sufficient background information for studying inference in stochastic processes. The book will cater to the need of a concise but clear and student-friendly book introducing, conceptually and computationally, basics of asymptotic inference.

Iberian World Empires and the Globalization of Europe 1415–1668 - Bartolome Yun Casalilla - Bog - Springer Verlag, Singapore - Plusbog.dk

Iberian World Empires and the Globalization of Europe 1415–1668 - Bartolome Yun Casalilla - Bog - Springer Verlag, Singapore - Plusbog.dk

This open access book analyses Iberian expansion by using knowledge accumulated in recent years to test some of the most important theories regarding Europe''s economic development. Adopting a comparative perspective, it considers the impact of early globalization on Iberian and Western European institutions, social development and political economies. In spite of globalization''s minor importance from the commercial perspective before 1750, this book finds its impact decisive for institutional development, political economies, and processes of state-building in Iberia and Europe. The book engages current historiographies and revindicates the need to take the concept of composite monarchies as a point of departure in order to understand the period''s economic and social developments, analysing the institutions and societies resulting from contact with Iberian peoples in America and Asia. The outcome is a study that nuances and contests an excessively-negative yet prevalent image of the Iberian societies, explores the difficult relationship between empires and globalization and opens paths for comparisons to other imperial formations.

Multiple Comparisons for Bernoulli Data - Taka Aki Shiraishi - Bog - Springer Verlag, Singapore - Plusbog.dk

Multiple Comparisons for Bernoulli Data - Taka Aki Shiraishi - Bog - Springer Verlag, Singapore - Plusbog.dk

This book focuses on multiple comparisons of proportions in multi-sample models with Bernoulli responses. First, the author explains the one-sample and two-sample methods that form the basis of multiple comparisons. Then, regularity conditions are stated in detail. Simultaneous inference for all proportions based on exact confidence limits and based on asymptotic theory is discussed. Closed testing procedures based on some one-sample statistics are introduced. For all-pairwise multiple comparisons of proportions, the author uses arcsine square root transformation of sample means. Closed testing procedures based on maximum absolute values of some two-sample test statistics and based on chi-square test statistics are introduced. It is shown that the multi-step procedures are more powerful than single-step procedures and the Ryan-Einot-Gabriel-Welsch (REGW)-type tests. Furthermore, the author discusses multiple comparisons with a control. Under simple ordered restrictions of proportions, the author also discusses closed testing procedures based on maximum values of two-sample test statistics and based on Bartholomew''s statistics. Last, serial gatekeeping procedures based on the above-mentioned closed testing procedures are proposed although Bonferroni inequalities are used in serial gatekeeping procedures of many.

Characterizing Interdependencies of Multiple Time Series - Kosuke Oya - Bog - Springer Verlag, Singapore - Plusbog.dk

Characterizing Interdependencies of Multiple Time Series - Kosuke Oya - Bog - Springer Verlag, Singapore - Plusbog.dk

This book introduces academic researchers and professionals to the basic concepts and methods for characterizing interdependencies of multiple time series in the frequency domain. Detecting causal directions between a pair of time series and the extent of their effects, as well as testing the non existence of a feedback relation between them, have constituted major focal points in multiple time series analysis since Granger introduced the celebrated definition of causality in view of prediction improvement. Causality analysis has since been widely applied in many disciplines. Although most analyses are conducted from the perspective of the time domain, a frequency domain method introduced in this book sheds new light on another aspect that disentangles the interdependencies between multiple time series in terms of long-term or short-term effects, quantitatively characterizing them. The frequency domain method includes the Granger noncausality test as a special case. Chapters 2 and 3 of the book introduce an improved version of the basic concepts for measuring the one-way effect, reciprocity, and association of multiple time series, which were originally proposed by Hosoya. Then the statistical inferences of these measures are presented, with a focus on the stationary multivariate autoregressive moving-average processes, which include the estimation and test of causality change. Empirical analyses are provided to illustrate what alternative aspects are detected and how the methods introduced here can be conveniently applied. Most of the materials in Chapters 4 and 5 are based on the authors'' latest research work. Subsidiary items are collected in the Appendix.
