Explicit positivity preserving numerical method for linear stochastic volatility models driven by -stable process
Xiaotong Li, Wei Liu, Xuerong Mao +2
In this paper, we introduce a linear stochastic volatility model driven by -stable processes, which admits a unique positive solution. To preserve positivity, we modify the clas…
Simple Proofs of the Summation and Connectivity Theorems in Metabolic Control Analysis
Weijiu Liu
In the early 1970s, the Kacser/Burns and the Heinrich/Rapoport groups independently discovered the important summation and connectivity theorems in metabolic control analysis. Thes…
Target Localization with a Coprime Multistatic MIMO Radar via Coupled Canonical Polyadic Decomposition Based on Joint EVD
Guo-Zhao Liao, Xiao-Feng Gong, Wei Liu +1
This paper addresses target localization using a multistatic multiple-input multiple-output (MIMO) radar system with coprime L-shaped receive arrays (CLsA). A target localization m…
High-Dimensional Covariate-Augmented Overdispersed Multi-Study Poisson Factor Model
Wei Liu, Qingzhi Zhong
Factor analysis for high-dimensional data is a canonical problem in statistics and has a wide range of applications. However, there is currently no factor model tailored to effecti…
Event-Triggered State Estimation Through Confidence Level
Wei Liu
This paper considers the state estimation problem for discrete-time linear systems under event-triggered scheme. In order to improve performance, a novel event-triggered scheme bas…
High-Dimensional Covariate-Augmented Overdispersed Poisson Factor Model
Wei Liu, Qingzhi Zhong
The current Poisson factor models often assume that the factors are unknown, which overlooks the explanatory potential of certain observable covariates. This study focuses on high…
