Published:Dec 29, 2025 11:34
1 min read
ArXiv

Analysis

This paper introduces a new class of flexible intrinsic Gaussian random fields (Whittle-Matérn) to address limitations in existing intrinsic models. It focuses on fast estimation, simulation, and application to kriging and spatial extreme value processes, offering efficient inference in high dimensions. The work's significance lies in its potential to improve spatial modeling, particularly in areas like environmental science and health studies, by providing more flexible and computationally efficient tools.

The Whittle likelihood for mixed models with application to groundwater level time series

Published:Dec 23, 2025 22:19
1 min read
ArXiv

Analysis

This article focuses on a specific statistical method (Whittle likelihood) and its application to a real-world problem (groundwater level time series analysis). The use of mixed models suggests a focus on handling complex data structures, likely incorporating both fixed and random effects. The source, ArXiv, indicates this is a pre-print or research paper, suggesting a technical and potentially specialized audience.

Red noise-based false alarm thresholds for astrophysical periodograms via Whittle's approximation to the likelihood

Published:Dec 20, 2025 04:06
1 min read
ArXiv

Analysis

This article describes a research paper focusing on a specific statistical method (Whittle's approximation) to improve the analysis of astrophysical data, particularly in identifying periodic signals in the presence of red noise. The core contribution is the development of more accurate false alarm thresholds. The use of 'periodograms' and 'red noise' suggests a focus on time-series analysis common in astronomy and astrophysics. The title is technical and targeted towards researchers in the field.
