Re-Examining Confidence Intervals for Ratios of Parameters
EconometricsThis paper considers the problem of constructing confidence intervals (CIs) for nonlinear functions of parameters, particularly ratios of parameters a common issue in econometrics and statistics.

Bootstrap Tests for Nonlinear Simplex Models
Stat, Volume 15, Issue 1, March 2026.ABSTRACT We provide important contributions regarding hypothesis tests on the class of nonlinear simplex regression models. The performance of traditional asymptotic tests based on the maximum likelihood estimation (MLE) tends to exhibit considerable size distortions in finite samples.

Stable Price Dispersion under Heterogeneous Buyer Consideration
The RAND Journal of Economics, Volume 57, Issue 1, Page 103-121, Spring 2026.ABSTRACT We study the pricing of homogeneous products sold to customers who consider different sets of suppliers. We identify prices that are stable in the sense that no firm wishes to undercut a rival or to raise its price when rivals are able to respond by offering special deals.

Estimation of parameters of finite population L-statistics
Nonlinear Analysis, 2013 We consider the estimation of important parameters of a linear combination of order statistics (L-statistic) in a finite population, emphasizing the influence of auxiliary information on the estimation accuracy.

Edgeworth Expansions for Semiparametric Averaged Derivatives [PDF]
Econometrica, 2000 Summary: A valid Edgeworth expansion is established for the limit distribution of density-weighted semiparametric averaged derivative estimates of single index models. The leading term that corrects the normal limit varies in magnitude, depending on the choice of bandwidth and kernel order.

Transactions of the Institute of British Geographers, Volume 51, Issue 1, March 2026.Abstract This article contributes empirical and conceptual insights to emerging debates on the regulation of short‐term rentals (STRs) by delving into the socio‐legal foundations of this housing market segment. Drawing on a qualitative study conducted between September 2022 and June 2023 focused on the governance of for‐profit temporary housing (i.e ...

Digital Twins and Applications, Volume 3, Issue 1, January/December 2026.The article proposes a digital twin‐driven probabilistic power flow framework that dynamically updates the probability distribution model parameters for wind, solar and load based on real‐time data. It combines the semi‐invariant method and Gram–Charlier series expansion to dynamically update the probability distribution of node voltages. ABSTRACT With

Complexity, Volume 2026, Issue 1, 2026.The Anthropocene has been a powerful conceptual lens for exploring the coupling of humans and the Earth system. While fostering a rich transdisciplinary discourse, its grounding in bounded geological time and emphasis on disruption has often reinforced the nature–culture divide and tended toward a dystopian outlook.

Advanced Materials Interfaces, Volume 12, Issue 24, December 22, 2025.A novel electric field‐assisted thermophoretic flame synthesis process enables rapid deposition of carbon nanoparticle films with tunable wettability. Applying a negative voltage during flame exposure accelerates growth, increases surface roughness, and alters morphology.
