Modulating Hunting Atmospheres: Mud and Material Flows Beyond the Kill

American Anthropologist, Volume 128, Issue 3, Page 629-639, September 2026.
ABSTRACT This article argues that hunting is not a bounded event but a materially redistributed atmosphere that extends beyond the kill and across field, truck, clothing, and home. Drawing on long‐term ethnographic fieldwork with wild boar hunters in Uruguay, I show how mud, odors, blood, and bodily residues carry the sensory, affective, and material ...

Edgeworth Expansions When the Parameter Dimension Increases with Sample Size

Econometrics
Suppose that we have a statistical model with q unknown parameters w, and an estimate w^, based on a sample of size n. A basic question is: what is the covariance of the estimate? The covariance is needed for the Central Limit Theorem (CLT). This gives a

Expansions for the Conditional Density and Distribution of a Standard Estimate

Stats
Conditioning is a very useful way of using correlated information to reduce the variability of an estimate. Conditioning an estimate on a correlated estimate, reduces its covariance, and so provides more precise inference than using an unconditioned ...

An Analogue to the Edgeworth–Esseen Expansion

Journal of Mathematical Analysis and Applications, 1998
Let \(f\) be a bounded, measurable function on \([-\pi, \pi]\) and let \((a_{n\nu}: \nu=0,\pm 1,\pm 2,\dots)\) be the Fourier coefficients of the powers \(f^n\) for \(n= 1,2,\dots\)\ .

Detecting Informed Trading Risk from Undercutting Activity

The Journal of Finance, Volume 81, Issue 4, Page 2109-2164, August 2026.
ABSTRACT We introduce a simple measure of informed trading risk, QIDres$QID^{res}$, the residual to liquidity quote‐improvement‐to‐deterioration ratio times −1$-1$. When facing with increased informed trading risk, liquidity providers compete less to provide liquidity, reducing their undercutting activity. Reductions in undercutting leave footprints in

On Aubin's Veto Mechanism: A Survey

Journal of Public Economic Theory, Volume 28, Issue 4, August 2026.
ABSTRACT We revisit Aubin's veto mechanism—known as the fuzzy veto—in which agents may participate in a blocking coalition with only a fraction of their endowments, and show that its Core‐Walras equivalence stems directly from the classical Debreu‐Scarf and Aumann theorems.

The Distribution and Quantiles of Sample Autocovariances and Autocorrelations of Sample Moments from a Stationary Process

Axioms
This paper gives expansions for the distribution, density and quantiles of any estimate that is a smooth function of the sample cross-moments of a stationary process.

Bed Topography and Subglacial Conditions of Denman Glacier, East Antarctica: Insights From Magnetotelluric Data and Interdisciplinary Studies

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 7, July 2026.
Abstract Understanding the basal conditions of East Antarctica's outlet glaciers is critical for accurately modeling future ice‐sheet evolution. Denman Glacier, one of the continent's fastest‐flowing glaciers, has been identified in bed‐topography models as occupying the deepest continental trough on Earth, potentially acting as a major outlet of the ...

On the Foundational Arguments of Sufficient Dimension Reduction

WIREs Computational Statistics, Volume 18, Issue 2, June 2026.
Contemporary Sufficient Dimension Reduction, a versatile method for extracting material information from data, can serve as a preprocessor for classical modeling and inference, or as a standalone theory that leads directly to statistical inference. ABSTRACT Sufficient dimension reduction (SDR) refers to supervised methods of dimension reduction that ...

New Methods for Multivariate Normal Moments

Stats
Multivariate normal moments are foundational for statistical methods. The derivation and simplification of these moments are critical for the accuracy of various statistical estimates and analyses.
