Advances in Modal Regression: From Theoretical Foundations to Practical Implementations

WIREs Computational Statistics, Volume 18, Issue 1, March 2026.
Modal regression. ABSTRACT Modal regression has emerged as a powerful alternative to traditional mean and quantile regression by focusing on estimating the conditional mode rather than the conditional mean or quantiles. This approach offers robustness to outliers and skewed distributions while providing more informative prediction intervals for ...

Demonstrating How FPCA Can Leverage SAR Time-Series Information to Distinguish Wetlands and Uplands Based on Seasonal Backscatter Trends

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Wetlands are important but vulnerable ecosystems that must be accurately mapped and monitored to effectively guide restoration and conservation planning. In this study, we used functional principal component analysis (FPCA) to leverage synthetic aperture

Survival on Image Regression With Application to Partially Functional Distributional Representation of Physical Activity

Statistical Analysis and Data Mining: An ASA Data Science Journal, Volume 19, Issue 1, February 2026.
ABSTRACT Technological advancements in wearable devices and medical imaging often lead to high‐dimensional physiological signals in the form of images or surfaces. To address these data structures, we develop a novel survival on image regression model with a specific focus on partially functional distributional representation of wearable data.

Patterns of chronic ethanol drinking in male and female cynomolgus monkeys

Alcohol, Clinical and Experimental Research, Volume 50, Issue 2, February 2026.
These studies in male and female cynomolgus monkeys replicate previous findings of a predictive relationship between characteristics of drinking during schedule induction and later open‐access drinking. Sex differences in daily patterns of ethanol intake were identified that may inform treatment approaches.

Recognition and Characterization of Forest Plant Communities through Remote-Sensing NDVI Time Series

Diversity, 2020
Phytosociology is a reference method to classify vegetation that relies on field data. Its classification in hierarchical vegetation units, from plant associations to class level, hierarchically reflects the floristic similarity between different sites ...

Distinguishing cancerous from non-malignant breast cells using viscoelastic creep and functional principal component analysis.

Journal of The Mechanical Behavior of Biomedical Materials
The mechanical responses and properties of breast epithelial cells are known to change during malignant transformation and progression due to the dynamics of their actin cytoskeleton network organization and the resulting viscoelastic deformability ...

Plant height defined growth curves can predict end of season maize yield

The Plant Phenome Journal, Volume 8, Issue 1, December 2025.
Abstract The development of quick, easy, and low‐cost methods to quantify within‐field variation is essential to successful implementation of mid‐season management for precision agriculture at scale. Temporal plant height and growth rates collected with unoccupied aerial vehicles mounted with red, green, blue sensors have the potential to predict ...
