Bayesian semiparametric approach to quantile nonlinear dynamic factor analysis models with mixed ordered and nonignorable missing data

Statistics (Berlin), 2022
In classical nonlinear dynamic factor analysis models (NDFAMs), we assume manifest variables follow the normal distribution. However, in some applications, the normality assumption may be unreasonable or questionable. This paper proposes a quantile NDFAM

Order does matter: recency effects in tourist satisfaction after multi-destination trips

Current Issues in Tourism, 2022
Whereas the drivers of tourist satisfaction with a destination have been largely studied, we know little about whether the serial order of the destination in multi-destination trips plays a role in explaining satisfaction.

Mediation analysis with causally ordered mediators using Cox proportional hazards model

Statistics in Medicine, 2018
Causal mediation analysis aims to investigate the mechanism linking an exposure and an outcome. However, studies regarding mediation effects on survival outcomes are limited, particularly in multi‐mediator settings.

Estimating Dynamic Probit Models with Higher-order Time- and Network-lag Structure and Correlated Random Effects

Many strategic choices in the social sciences involve sluggish adjustment with an ex-ante unknown lag structure as well as patterns of interdependency among the cross-sectional units, which call for a flexible parameterization based on multiple networks. This chapter proposes straightforward panel-probit estimation approaches based on control functions

Investigating factors affecting injury severities of drivers with low route familiarity level in mountainous highways single-vehicle crashes under different lighting conditions

Lighting Research & Technology
Mountainous highway single-vehicle crashes present higher fatality rate and are associated with relative poor lighting condition and driver’s route familiarity. This study examined three-year mountainous highway single-vehicle crashes to identify factors

Identifying factors affecting crash injury severity of pillion riders using interpretable machine learning techniques

International Journal of Injury Control and Safety Promotion
In India, motorized two-wheeler (TW) riders account for 44.5% of fatal road crashes. While factors affecting drivers have been studied, research on pillion riders’ injury severity remains limited.

Applying hybrid dimension reduction and econometric model to investigate rider behaviors in roadway departure motorcycle crashes

Transportation letters
This study analyzed 3,234 motorcycle roadway‑departure crashes recorded in Louisiana from 2017 to 2021. The dataset spans crash, vehicle, environmental, and location variables, enabling a comprehensive assessment of factors shaping injury severity.
