Does Global Value Chain Participation Matter for Economic Upgrading? A Nonlinear Insight

The World Economy, Volume 49, Issue 5, Page 922-936, May 2026.
ABSTRACT In recent decades, global value chains (GVCs) have come to dominate much of world trade. Participation in GVCs is widely regarded as a key driver of development by enabling countries to climb the value‐added ladder. However, tighter governance structures within GVCs can make these benefits uncertain.

Statistical Analysis of Stochastic Resonance in a Thresholded Detector

Austrian Journal of Statistics, 2016
A subthreshold signal may be detected if noise is added to the data. The noisy signal must be strong enough to exceed the threshold at least occasionally; but very strong noise tends to drown out the signal.

Model‐Free Local Partial Correlation

Australian &New Zealand Journal of Statistics, Volume 68, Issue 1, March 2026.
ABSTRACT In the simple linear regression context, partial correlation measures the linear association between two variables, with the linear effects of a third control variable removed. In this paper, we investigate the local partial correlation using a kernel smoothing approach.

A Comparison of some non-parametric kernel estimators using simulations

Ibn Al-Haitham Journal for Pure and Applied Sciences
         In this research, we conducted a comprehensive investigation of various kernel functions employed in the estimation of nonparametric regression functions. In particular, we investigated the Nadaraya-Watson method and local polynomial regression

Cumulative Differences Between Paired Samples

Statistical Analysis and Data Mining: An ASA Data Science Journal, Volume 19, Issue 1, February 2026.
ABSTRACT Paired samples are observations from two populations, commonly with each observed response from one population corresponding to an observed response from the other population at the same value of an ordinal covariate. Such pairs of responses at the same covariate values are called “matched pairs.” Graphing cumulative differences between the ...

Inference About Separable Causal Effects With Longitudinal Bivariate Ordinal Responses With Missingness and Censoring

Statistics in Medicine, Volume 45, Issue 3-5, February 2026.
ABSTRACT Causal inference has gained extensive attention in various fields, including healthcare, epidemiology, and social sciences. While many methods have been developed, most research has been directed to handle data with a univariate response variable.

Endogeneity Corrections in Binary Outcome Models With Nonlinear Transformations: Identification and Inference

Oxford Bulletin of Economics and Statistics, Volume 88, Issue 1, Page 45-56, February 2026.
ABSTRACT For binary outcome models, an endogeneity correction based on nonlinear rank‐based transformations is proposed. Identification without external instruments is achieved under one of two assumptions: Either the endogenous regressor is a nonlinear function of one component of the error term, conditional on the exogenous regressors, or the ...

On a Nadaraya-Watson Estimator with Two Bandwidths [PDF]

, 2020
In a regression model, we write the Nadaraya-Watson estimator of the regression function as the quotient of two kernel estimators, and propose a bandwidth selection method for both the numerator and the denominator.
