Nonparametric Survival Estimation With Contaminated and Adjudicated Events

open access: yesScandinavian Journal of Statistics, EarlyView.
ABSTRACT We study the conditional expert Kaplan–Meier estimator, an extension of the classical Kaplan–Meier estimator designed for time‐to‐event data subject to both right‐censoring and contamination. Such contamination, where observed events may not reflect true outcomes, is common in applied settings, including insurance and credit risk, where expert

Is the World Getting Smaller? Network‐Driven Heterogeneity in Gravity‐Model Elasticities

open access: yesThe World Economy, EarlyView.
ABSTRACT Gravity models constitute the workhorse of empirical international trade research, yet the temporal stability of their core parameters—distance and GDP elasticities—remains underexplored, particularly in relation to the evolving structure of trade networks.

How many people are employed in South Africa?

open access: yesSouth African Journal of Economics, Volume 94, Issue 4, December 2026.
ABSTRACT The main labour market survey in South Africa is the Quarterly Labour Force Survey (QLFS) but the General Household Survey (GHS) also measures employment.

Frequency‐dependent contraction rates for the Bayesian method to the inverse source problem

open access: yesTransactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract This paper addresses an inverse source problem for acoustic waves in a range of frequencies. Our study has two main goals. First, although the problem is severely ill‐posed with a logarithmic stability estimate, we demonstrate, through careful analysis of the forward map's singular values, that increasing the frequency range enhances stability,

A Re‐Appraisal of Three Network Meta‐Analyses to Explain the Discrepancy in Findings for the Efficacy of Fluoxetine for the Treatment of Depression in Children and Adolescents

open access: yesCochrane Evidence Synthesis and Methods, Volume 4, Issue 6, November 2026.
ABSTRACT Objective To explain discrepant findings for fluoxetine's efficacy in three influential network meta‐analyses (NMAs) of treatments for pediatric depression, which led to conflicting clinical recommendations. Design Critical appraisal and re‐analysis of three published NMAs.
