Integrative Bayesian tensor regression for imaging genetics applications

open access: yesFrontiers in Neuroscience, 2023
Identifying biomarkers for Alzheimer's disease with a goal of early detection is a fundamental problem in clinical research. Both medical imaging and genetics have contributed informative biomarkers in literature.

Parametric Frailty Analysis in Presence of Collinearity: An Application to Assessment of Infant Mortality

open access: yesMathematics, 2022
This paper analyzes the time to event data in the presence of collinearity. To address collinearity, the ridge regression estimator was applied in multiple and logistic regression as an alternative to the maximum likelihood estimator (MLE), among others.

Hox genes in the coordination of embryonic development. Model of hourglass in the description of vertebrate ontogenesis

open access: yesJournal of Education, Health and Sport, 2021
The paper analyzes the role of HOX genes in the processes of embryonic development of vertebrates. Based on the analysis, it is concluded that HOX genes are the most important regulators of embryonic development.

Controlling for body size leads to inferential biases in the biological sciences

open access: yesEvolution Letters, 2020
Many traits correlate with body size. Studies that seek to uncover the ecological factors that drive evolutionary responses in traits typically examine these responses relative to associated changes in body size using multiple regression analysis ...

Exploring Efficient Methods for Using Multiple Spectral Reflectance Indices to Establish a Prediction Model for Early Drought Stress Detection in Greenhouse Tomato

open access: yesHorticulturae, 2023
Early detection of drought stress in greenhouse tomato (Solanum lycopersicum) is an important issue. Real-time and nondestructive assessment of plant water status is possible by spectroscopy.

Collinear superspace

open access: yesPhysical Review D, 2016
This letter provides a superfield based approach to constructing a collinear slice of $\mathcal{N}$ = 1 superspace. The strategy is analogous to integrating out anti-collinear fermionic degrees-of-freedom as was developed in the context of soft-collinear effective theory.

On the adaptive elastic-net with a diverging number of parameters [PDF]

open access: yes, 2009
We consider the problem of model selection and estimation in situations where the number of parameters diverges with the sample size. When the dimension is high, an ideal method should have the oracle property [J. Amer. Statist. Assoc.

ISOSCELES TRIANGLES ON THE SIDES OF A TRIANGLE

open access: yesHuman Research in Rehabilitation, 2019
Famous construction of Fermat-Toricelly point of a triangle leads to the question is there a similar way to construct other isogonic centers of a triangle in a similar way.

Significance Regression: Robust Regression for Collinear Data [PDF]

open access: yes, 1993
This paper examines robust linear multivariable regression from collinear data. A brief review of M-estimators discusses the strengths of this approach for tolerating outliers and/or perturbations in the error distributions.
