Portfolio‐Level Reliability Analysis of a Multi‐Asset System: A Frailty Proportional Intensity Modeling Framework

open access: yesQuality and Reliability Engineering International, EarlyView.
ABSTRACT Understanding and modeling the equipment failure behavior is crucial for reducing downtime, optimizing maintenance strategies, and improving operational safety. This challenge becomes particularly critical in industrial contexts involving multi‐asset portfolios, where heterogeneous conditions influence the reliability of individual assets and,

Personalized treatment selection via the covariate-specific treatment effect curve for longitudinal data

open access: yesStatistical Theory and Related Fields, 2021
Treatment selection based on patient characteristics has been widely recognised in modern medicine. In this paper, we propose a generalised partially linear single-index mixed-effects modelling strategy for treatment selection and heterogeneous treatment

Financial Inclusion, Energy Transition, and Sustainable Development in Sub‐Saharan Africa: A Distributional Panel Analysis

open access: yesSustainable Development, EarlyView.
ABSTRACT Sub‐Saharan Africa (SSA) faces pressing financing and structural transitions to achieve the 2030 Agenda, yet the distributional relationships linking financial inclusion and renewable energy adoption to sustainable development goal (SDG) achievement remain underexplored. This study investigates the roles of multidimensional financial inclusion

Longitudinal Survival Analysis Using First Hitting Time Threshold Regression: With Applications to Wiener Processes

open access: yesStats
First-hitting time threshold regression (TR) is well-known for analyzing event time data without the proportional hazards assumption. To date, most applications and software are developed for cross-sectional data. In this paper, using the Markov property

Local Eviction Moratoria and the Spread of COVID‐19

open access: yesSouthern Economic Journal, EarlyView.
ABSTRACT At different stages during the initial onset of the COVID‐19 pandemic, various US states and local municipalities enacted eviction moratoria. One of the main aims of these moratoria was to slow the spread of COVID‐19 infections. We deploy a semiparametric difference‐in‐differences approach with an event study specification to examine whether ...

Regulation, Taxation, and Resources: Unpacking Greenhouse Gas Emission Drivers Across G7 Economies

open access: yesThunderbird International Business Review, EarlyView.
ABSTRACT Advanced economies are under growing pressure to downscale greenhouse gas (GHG) emissions without undermining growth, yet G7 (Group of Seven) nations, representing almost 10% of the world's population, still generate one quarter of global GHGs.

An asymptotic theory for model selection inference in general semiparametric problems. [PDF]

open access: yes
Recently, Hjort and Claeskens (2003) developed an asymptotic theory for model selection, model averaging and post-model selection/averaging inference using likelihood methods in parametric models, along with associated confidence statements.

Nonparametric and semiparametric methods for economic research [PDF]

open access: yes, 1992
Developments in the vast and growing literatures on nonparametric and semiparametric statistical estimation are reviewed. The emphasis is on useful methodology rather than statistical properties for their own sake. Some empirical applications to economic

Computing Nonparametric Functional Estimates in Semiparametric Problems [PDF]

open access: yes, 1992
The purpose of this note is to provide a brief account of available FORTRAN Routines for computing nonparametric functional estimates, Frequently used in semiparametric problems, evaluated at each data point. Then semiparametric estimates can be computed

Semiparametric Estimation of Single-Index Transition Intensities [PDF]

open access: yes
This research develops semiparametric kernel-based estimators of state-specific conditional transition intensities, h(y|x), for duration models with right-censoring and/or multiple destinations (competing risks).
