Метод обнаружения структурного сдвига в модели авторегрессионной условной гетероскедастичности: случай распределения Стьюдента
Математическое моделирование. 2023. Т. 35. № 1. С. 51–58.
We consider two methods of structural break detection in a piecewise generalized model of autoregressive conditional heteroscedasticity. The first method is based on Kolmogorov–Smirnov statistics and is called KS-method. The second one is based on the cumulative sums and is called KL-method. In this paper, we compare the KS- and KL-methods under the assumption of Student conditional distribution of random errors. The results of our Monte Carlo experiments were as follows: the KL-method lost to the KS-method both in terms of the average probability of first type error and in terms of the average power structural break detection.

The global transportation sector is undergoing a major transformation associated with the transition to a low-carbon economy and the expanded use of alternative energy sources. In recent decades, the substitution of petroleum-based motor fuels with their substitutes – primarily biofuels and electric power (electric vehicles) – in light-duty road transport has accelerated. Public policy at ...

The year 2025 was marked by deepening contradictions between the leading world powers in world politics and economics. The dominant paradigm is the transition of the world's leading players, primarily the United States, to fierce competition in order to promote and realize national interests. In this context, political polarization has increased in many countries of ...

We consider 3-diffeomorphisms with source–sink dynamics where Smale solenoids play the role of the source and the sink (NSSS-diffeomorphisms). It is known that such diffeomorphisms exist only on lens spaces. On the 3-sphere, every NSSS-diffeomorphism is associated with an exchangeable braid. An exchangeable braid with the strand number n was constructed for each n 3 in such a way ...

Гомеоморфизмы топологических пространств называются эквивалентными по надстройке, если надстройки над ними топологически эквивалентны. В частности, топологически сопряженные гомеоморфизмы эквивалентны по надстройке. Известно, что для гомологически неприводимых гомеоморфизмов их топологическая сопряженность является необходимым и достаточным условием их эквивалентности по надстройке. Тогда как инварианты топологической сопряженности гомологически приводимых гомеоморфизмов во многих случаях являются избыточными для эквивалентности по ...

Elaborating on Welzel et al.'s "Cool Water Theory," our study zooms into the more limited (albeit still varied) framework conditions of Russia's huge territory. Within Russia's confines, we examine how the combination of moderately cool seasons with steady rain (i.e., Cool Water) affects sub-national areas' contemporary societal progress in two modernization indicators: material prosperity in ...

Digital public procurement is increasingly implemented through e-procurement platforms, yet evidence on the governance capabilities needed to deliver transparency, coordination and organisational learning remains limited outside high-capacity contexts. This article reframes public procurement as a socio-technical platform ecosystem and develops an ecosystem capability framework that links three tiers (government, platform operators and users) to three ...

Small and medium-sized enterprises (SMEs) operate under conditions of chronic resource constraints, which makes it important to study strategies capable of transforming available resources into sustainable financial outcomes. One such strategy is entrepreneurial bricolage - the unconventional recombination of existing resources to address organizational challenges. This article examines the impact of bricolage on SME performance, ...

Industrial policy has gained momentum over the past 15 years in both developed and developing countries. It is now seen as a tool not only to support economic growth and cope with unemployment but also to accelerate the digitalization of economies and the “green” transition. However, there is no consensus among experts regarding the optimal ...

Внешние ограничения затронули преобладающую часть сегментов производственной деятельности, но по-разному. Выделено шесть групп секторов в зависимости от прогнозных оценок эффекта санкций – от крайне негативного до умеренно положительного влияния. Большинство секторов испытало значительное негативное воздействие, включая ...

Данные модели могут использовать грубые упрощения для ускорения и упрощения вычисления требований по открытым позициям. В число таких упрощений входят: ограничение набора учитываемых риск-факторов, использование простых функций распределения и предположение о нулевой или фиксированной корреляции между риск-факторами.

This study raises the problem of modeling conditional volatility under the random shocks’ normality assumption violation. To obtain more accurate estimates of GARCH process parameters and conditional volatilities, we propose two semi-nonparametric GARCH models. The implementation of the proposed methods is based on an adaptation of the [Gallant, Nychka, 1987] semi-nonparametric method to the family ...

We proposed the new method (GARCH-M-LEV) that allows capturing the asymmetry both in the variance and return equations. The development of the model is encouraged by the stylized fact that investors demand a higher risk premium during ”bad” volatility periods rather than ”good” ones. To study the properties of the obtained estimators, we conducted a ...
