KS-метод обнаружения структурного сдвига в GARCH(1,1) моделях
В работе предложен новый метод обнаружения одного структурного сдвига в GARCH(1,1) модели, основанный на статистике Колмогорова–Смирнова. Хорошие свойства предлагаемого метода подкрепляются численными экспериментами. Метод сопоставляется с тремя широко известными CUSUM-методами обнаружения структурных сдвигов в GARCH моделях: KL (Kokoszka, Leipus, 1999), IT (Inclán, Tiao, 1994) и LTM (Lee et al., 2004). Для генерации GARCH процессов использовались временные ряды доходностей 26 российских ценных бумаг. На основе проведенных экспериментов показано, что предлагаемый метод обладает высокой конкурентоспособностью и занимает в некотором смысле «компромиссное» положение между KL-методом, имеющим высокие мощность и вероятность ошибки первого рода, и IT- и LTM-методами, мощность и вероятности ошибок первого рода которых низки.

Моделирование пространственной зависимости миграционных потоков выпускников вузов РФ
В данной работе представлены результаты моделирования миграционных процессов выпускников вузов РФ, в том числе с учетом влияния пространственного эффекта соседних регионов. Значимыми факторами миграции выпускников являются более высокий уровень доходов, ВРП на душу населения и уровень безработицы в принимающем регионе. С помощью инструментария пространственной эконометрики доказано наличие положительной пространственной автокорреляции по оттоку и притоку выпускников между соседними регионами.

3D Shape Analysis. Fundamentals, Theory, and Applications
An in-depth description of the state-of-the-art of 3D shape analysis techniques and their applications This book discusses the different topics that come under the title of «3D shape analysis». It covers the theoretical foundations and the major solutions that have been presented in the literature. It also establishes links between solutions proposed by different communities that studied 3D shape, such as mathematics and statistics, medical imaging, computer vision, and computer graphics. The first part of 3D Shape Analysis: Fundamentals, Theory, and Applications provides a review of the background concepts such as methods for the acquisition and representation of 3D geometries, and the fundamentals of geometry and topology. It specifically covers stereo matching, structured light, and intrinsic vs. extrinsic properties of shape. Parts 2 and 3 present a range of mathematical and algorithmic tools (which are used for e.g., global descriptors, keypoint detectors, local feature descriptors, and algorithms) that are commonly used for the detection, registration, recognition, classification, and retrieval of 3D objects. Both also place strong emphasis on recent techniques motivated by the spread of commodity devices for 3D acquisition. Part 4 demonstrates the use of these techniques in a selection of 3D shape analysis applications. It covers 3D face recognition, object recognition in 3D scenes, and 3D shape retrieval. It also discusses examples of semantic applications and cross domain 3D retrieval, i.e. how to retrieve 3D models using various types of modalities, e.g. sketches and/or images. The book concludes with a summary of the main ideas and discussions of the future trends. 3D Shape Analysis: Fundamentals, Theory, and Applications is an excellent reference for graduate students, researchers, and professionals in different fields of mathematics, computer science, and engineering. It is also ideal for courses in computer vision and computer graphics, as well as for those seeking 3D industrial/commercial solutions.

Robust Statistics. Theory and Methods (with R)
A new edition of this popular text on robust statistics, thoroughly updated to include new and improved methods and focus on implementation of methodology using the increasingly popular open-source software R. Classical statistics fail to cope well with outliers associated with deviations from standard distributions. Robust statistical methods take into account these deviations when estimating the parameters of parametric models, thus increasing the reliability of fitted models and associated inference. This new, second edition of Robust Statistics: Theory and Methods (with R) presents a broad coverage of the theory of robust statistics that is integrated with computing methods and applications. Updated to include important new research results of the last decade and focus on the use of the popular software package R, it features in-depth coverage of the key methodology, including regression, multivariate analysis, and time series modeling. The book is illustrated throughout by a range of examples and applications that are supported by a companion website featuring data sets and R code that allow the reader to reproduce the examples given in the book. Unlike other books on the market, Robust Statistics: Theory and Methods (with R) offers the most comprehensive, definitive, and up-to-date treatment of the subject. It features chapters on estimating location and scale; measuring robustness; linear regression with fixed and with random predictors; multivariate analysis; generalized linear models; time series; numerical algorithms; and asymptotic theory of M-estimates. Explains both the use and theoretical justification of robust methods Guides readers in selecting and using the most appropriate robust methods for their problems Features computational algorithms for the core methods Robust statistics research results of the last decade included in this 2nd edition include: fast deterministic robust regression, finite-sample robustness, robust regularized regression, robust location and scatter estimation with missing data, robust estimation with independent outliers in variables, and robust mixed linear models. Robust Statistics aims to stimulate the use of robust methods as a powerful tool to increase the reliability and accuracy of statistical modelling and data analysis. It is an ideal resource for researchers, practitioners, and graduate students in statistics, engineering, computer science, and physical and social sciences.
