Robust estimation of the Hurst parameter and selection of an onset scaling. [PDF]

open access: yes, 2009
We consider the problem of estimating the Hurst parameter for long-range dependent processes using wavelets. Wavelet techniques have been shown to effectively exploit the asymptotic linear relationship that forms the basis of constructing an estimator ...

Estimation of a structural parameter in the presence of a large number of nuisance parameters [PDF]

open access: yesBiometrika, 1984
This paper considers asymptotic lower bounds for the asymptotic variance of estimators when there are nuisance parameters whose number increases in proportion to the sample size. A lower bound is established for the subclass of estimator sequences, whose stochastic expansion satisfies a certain condition.

Asymptotics of Solutions of the Generalized Hutchinson’s Equation

open access: yesМоделирование и анализ информационных систем, 2015
We discuss the dynamics of the Hutchinson’s equation and its generalizations. An estimate of the global stability region of a positive steady state is obtained. The main results refer to existence, stability and asymptotics of a slow oscillating solution.

Relaxation Cycles in a Model of Synaptically Interacting Oscillators

open access: yesМоделирование и анализ информационных систем, 2017
In this paper the mathematical model of a neural network with a ring synaptic interaction elements is considered. The model is a system of scalar nonlinear differential-difference equations, the right parts of which depend on a large parameter. The unknown

The effect of geographical clustering on parameter estimation and ranking of individuals in large scale assessments [PDF]

open access: yesروان‌شناسی تربیتی, 2021
The aim of this study was to investigate the effect of geographical clustering on the estimation of ability parameter (before ranking) as well as the ranking of examinees in large-scale tests (such as national university entrance examination). The design

Synchronization in networked systems with large parameter heterogeneity

open access: yesCommunications Physics, 2023
Systems that synchronize in nature are intrinsically different from one another, with possibly large differences from system to system. While a vast part of the literature has investigated the emergence of network synchronization for the case of small ...

Advances and visions in large-scale hydrological modelling : findings from the 11th Workshop on Large-Scale Hydrological Modelling [PDF]

open access: yes, 2008
Large-scale hydrological modelling has become increasingly wide-spread during the last decade. An annual workshop series on large-scale hydrological modelling has provided, since 1997, a forum to the German-speaking community for discussing recent ...

Relaxation Oscillations in a System with Delays Modeling the Predator-Prey Problem

open access: yesМоделирование и анализ информационных систем, 2013
A new asymptotic method for investigating complex relaxation oscillations of a system with delay was offered. Applying it, we can reduce the problem of predator-prey system dynamics to problem of one-dimensional maps analysis.
