JOURNAL OF TIME SERIES ANALYSIS 2023年 第1期44卷 125-147页
作者: Sundararajan, Raanju R. Barreto-Souza, Wagner Southern Methodist Univ Dept Stat Sci Dallas TX USA King Abdullah Univ Sci & Technol Stat Program Thuwal Saudi Arabia
A new robust stochastic volatility (SV) model having Student-t marginals is proposed. Our process is defined through a linear normal regression model driven by a latent gamma process that controls temporal dependence.... 详细信息

The multilevel hierarchical data em-algorithm. Applications to discrete-time Markov chain epidemic models
收藏 引用
HELIYON 2022年 第12期8卷 e12622页
作者: Wanduku, Divine Georgia Southern Univ Dept Math Sci 65 Georgia AveRoom 3309 Statesboro GA 30460 USA
The theory of multilevel hierarchical data Expectation Maximization (em)-algorithm is introduced via discrete time Markov chain (DTMC) epidemic models. A general model for a multilevel hierarchical discrete data is de... 详细信息

Parametric estimation and robust inference for current status data with Lindley lifetimes
收藏 引用
COMMUNICATIONS IN STATISTICS-SIMULATION AND COMPUTATION 2025年
作者: Castilla, Elena Rey Juan Carlos Univ Dept Matemat Aplicada Mostoles Campus Madrid 28933 Spain
Current status data appear in many biomedical studies when we only know if an event of interest occurs before or after a specific time point. In this paper, we develop statistical inference for the estimation of param... 详细信息

STOCHASTIC MODELS 2024年 第1期40卷 1-37页
作者: Bladt, Martin Gardner, Clara Brimnes Univ Copenhagen Dept Math Sci Copenhagen Denmark Tech Univ Denmark DTU Compute Lyngby Denmark Tech Univ Denmark DTU Compute DK-2800 Lyngby Denmark
In this paper, we introduce a bivariate distribution on R(+)xN arising from a single underlying Markov jump process. The marginal distributions are phase-type and discrete phase-type distributed, respectively, which a... 详细信息
