n this paper, we focus on the generalization of the Hurst empirical law and suggest a set of reduced parameters for quantitative description of long-time series. These series are usually considered as a specific response of a complex system (economic, geophysical, electromagnetic and other systems), where successive fixations of external factors become impossible. We consider ...

Внедрение системы маржирования на рынках производных финансовых инструментов положительно сказывается на ликвидности рынка и эффективности рыночного ценообразования. При этом при оценке маржинальных требований не учитываются в полной мере диверсификация и хеджирование портфеля. Поэтому для соответствия регуляторным требованиям биржа устанавливает завышенный размер маржи.
В исследовании Daskalaki, Skiadopoulos (2016 г.) было доказано, что завышение маржинальных требований снижает положительный ...

Automated analysis of complex systems based on multiple readouts remains a challenge. Change point detection algorithms are aimed to locating abrupt changes in the time series behaviour of a process. In this paper, we present a novel change point detection algorithm based on Latent Neural Stochastic Differential Equations (SDE). Our method learns a non-linear deep ...

В настоящем учебнике «Эконометрика» рассматривается как дисциплина, объединяющая совокупность результатов, методов и приемов экономической теории, экономической статистики и математико-статистического инструментария для количественного выражения качественных закономерностей. Курс эконометрики призван научить различным способам выражения связей и закономерностей через эконометрические модели, основанные на данных статистических наблюдений. Эконометрический подход предусматривает анализ соответствия выбранной модели изучаемому объекту, рассмотрению причин, приводящих ...

Introduction. Possibilities of application ARIMA-models to analysis and forecasting of demographic time series were considered in the article. Foreign studies had shown that the ARIMA-models give good results for forecasting indicators such as population, birth rates and death rates, life expectancy, along with the traditional demographic methods (cohort-component approach). Research technique. Box-Jenkins methodology of the ...

Рассматриваются методы и алгоритмы построения эконометрических моделей по пространственным, временным и пространственно-временным выборкам, методы оценки параметров моделей и проверки их значимости. Изложение регрессионного анализа начинается с классической двумерной и множественной линейной модели, которая в дальнейшем обобщается на условия мультиколлинеарности и нелинейности, гетероскедастичности и автокоррелированности регрессионных остатков. Рассматриваются также модели с переменной структурой, бинарного и множественного ...

This paper considers a seasonal adjustment procedure that is capable of preparing data to the use in applied general equilibrium models. It is shown that standard seasonal adjustment procedures do not satisfy the property of invariance to deflating, that hinders their use in applied general equilibrium models. A system of axioms that describes the desired ...
