Stochastic fixed-point equation and local dependence measure [PDF]

open access: yesThe Annals of Applied Probability, 2020
We study solutions to the stochastic fixed point equation $X\stackrel{d}{=}AX+B$ where the coefficients $A$ and $B$ are nonnegative random variables. We introduce the ``local dependence measure'' (LDM) and its Legendre-type transform to analyze the left ...

Parameter Estimation of KST-IRT Model under Local Dependence

open access: yesPsych, 2023
A mantra often repeated in the introductory material to psychometrics and Item Response Theory (IRT) is that a Rasch model is a probabilistic version of a Guttman scale. The idea comes from the observation that a sigmoidal item response function provides

Food Production and Consumption in Ordos of Inner Mongolia

open access: yesFoods, 2023
Ordos is an ecological fragile area in the upstream and midstream of the Yellow River and a component of the ecological security barrier on the northern frontier of China. With population growth in recent years, the contradiction between human beings and

Nonparametric Directional Dependence Estimation and Its Application to Cryptocurrency

open access: yesAxioms, 2023
This paper proposes a nonparametric directional dependence by using the local polynomial regression technique. With data generated from a bivariate copula having a nonmonotone regression structure, we show that our nonparametric directional dependence is

Copula-based local dependence among energy, agriculture and metal commodities markets

open access: yesEnergy, 2020
This paper studies the extreme dependencies among energy, agriculture and metal commodities markets, with an emphasis on local co-movements. By applying a novel, copula-based, local Kendall's tau approach to measure nonlinear local dependence in regions,

Modeling Local Dependence in Natural Language with Multi-channel Recurrent Neural Networks [PDF]

open access: yesAAAI Conference on Artificial Intelligence, 2018
Recurrent Neural Networks (RNNs) have been widely used in processing natural language tasks and achieve huge success. Traditional RNNs usually treat each token in a sentence uniformly and equally.

The role of path-dependence in the local economic transformation [PDF]

open access: yesZbornik Radova: Geografski institut "Jovan Cvijić", 2015
The examination focuses on the issue of path-dependence, which is considered to be the core concept of evolutionary economic geography emphasizing the importance of historical development.

Global polarization and spin alignment measurements [PDF]

open access: yesEPJ Web of Conferences, 2022
Recent experimental results on global polarization of hyperons and spin alignment of vector mesons in heavy-ion collisions are reviewed, especially in context of the energy dependence and particle species dependence.

Element dependence of local disorder in medium-entropy alloy CrCoNi

open access: yesAIP Advances, 2021
The medium-entropy alloy CrCoNi is known to have exceptional mechanical properties. To clarify its local structure, we performed extended x-ray absorption fine structure measurement of CrCoNi.

Local Dependence for Bivariate Weibull Distributions Created by Archimedean Copula

open access: yesمجلة بغداد للعلوم, 2021
In multivariate survival analysis, estimating the multivariate distribution functions and then measuring the association between survival times are of great interest.
