A goodness‐of‐fit test for regression models with discrete outcomes

Canadian Journal of Statistics, Volume 54, Issue 2, June 2026.
Abstract Regression models are often used to analyze discrete outcomes, but classical goodness‐of‐fit tests such as those based on the deviance or Pearson's statistic can be misleading or have little power in this context. To address this issue, we propose a new test, inspired by the work of Czado et al.

Methods to estimate marine functional connectivity: A primer

Ecological Applications, Volume 36, Issue 4, June 2026.
Abstract Organism movement is a key process in the transfer of individuals, genes, functional traits, matter, and energy among habitat patches, at sea and across the land–sea interface. The resulting fluxes, collectively termed marine functional connectivity (MFC), underpin planetary health and an array of ecosystem services.

An Empirical Investigation of Adaptive Cognitive Guidance Strategy Optimization Driven by Hierarchical Chain‐of‐Thought Reasoning in Large Language Models

Engineering Reports, Volume 8, Issue 6, June 2026.
This study proposes an adaptive cognitive counseling strategy based on hierarchical thinking chain. This strategy constructs a three‐layer reasoning framework consisting of strategy layer, tactics layer, and detail layer, and decomposes complex problems into operational cognitive units.

Quadratic Hedging of American Options Under GARCH Models

Journal of Futures Markets, Volume 46, Issue 6, Page 1079-1097, June 2026.
ABSTRACT American options are widely traded in financial markets, yet there is a scarcity of literature on hedging in incomplete markets. In this paper, we derive optimal hedging ratios and option values using Local Risk Minimization (LRM) and Global Risk Minimization (GRM) hedging strategies through dynamic programming.

Regionalizing the food dollar

Journal of the Agricultural and Applied Economics Association, Volume 5, Issue 2, Page 211-223, June 2026.
Abstract This study spatially extends the USDA's Food Dollar framework, analyzing food expenditure distribution across regional economies. Using regional SAMs and county‐level data, we estimate farm shares, industry contributions, and food dollar multipliers. Results reveal significant geographic disparities, with processing shares ranging from over 25%
