The Non-Normal Bivariate Distribution

, 1972
The construction of bivariate and multivariate distributions is a subject which has attracted attention over a long period of time, and most thinking of bivariate distribution is centered around the normal case. It has I only been in the past two decades

Advances in vital‐sign prediction and early‐warning models for underground coal mine workers integrating environmental factors

Deep Underground Science and Engineering, EarlyView.
This review synthesizes advances in predicting miners' vital signs by integrating environmental monitoring (dust, temperature, and gas) with physiological data. It highlights multi‐source data fusion techniques and early‐warning models for enhanced occupational safety in underground coal mines.

Statistical Analysis of the Possibility of Hail in Northern Zagros [PDF]

تحقیقات کاربردی علوم جغرافیایی
In examining natural hazards, such as hail, statistical analyzes can play a significant role. Due to the great importance of economic and side losses of hail in the northern part of Zagros with maximum frequency and damage, the necessity of studying its ...

Probabilistic prediction of rate‐dependent rock strength using natural gradient boosting and Gaussian process regression

Deep Underground Science and Engineering, EarlyView.
Probabilistic natural gradient boosting and Gaussian process regression models accurately predict rate‐dependent rock strength across lithologies. Static strength and strain rate dominate, while geometric factors have minimal influence, enabling interpretable and uncertainty‐aware predictions for dynamic geomechanical applications. Abstract The dynamic

THE BIVARIATE POWER-NORMAL DISTRIBUTION

, 2002
In this paper, the earlier work on so-called \u22power-normal distribution\u22 is extended to a multivariate case, especially focusing on a bivariate one.

Self‐Reported Versus Objectively Logged Social Media Use: Implications for Measurement in Eating Disorder Research

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Self‐reported frequency measures of social media use (e.g., “How often do you use social media?”) are convenient, yet their criterion validity against objective behavioral data remains largely untested in eating disorder research. We compared self‐reports of TikTok use with objective data extracted from TikTok datafiles.

On Bivariate Distributions with Singular Part

Axioms
There are many families of bivariate distributions with given marginals. Most families, such as the Farlie–Gumbel–Morgenstern (FGM) and the Ali–Mikhail–Haq (AMH), are absolutely continuous, with an ordinary probability density. In contrast, there are few families with a singular part or a positive mass on a curve.

Associations Between Microbial Depletion and Autonomic Dysregulation in Binge‐Eating Disorder

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective The interplay between the gut microbiome and autonomic nervous system remains unexplored in binge‐eating disorder (BED). We aimed to explore specific microbial alterations in BED and examine their potential association with cardiac vagal tone as a distinct bio‐behavioral phenotype.

Scrutinizing the Wallacean shortfall: global gaps in snake occurrence data across space and environment

Ecography, EarlyView.
Occurrence records are fundamental for ecological and evolutionary research, providing key information on species' geographic ranges. However, these records are often taxonomically, spatially, and temporally biased, requiring caution in their use. Here, we analysed the spatial coverage of occurrence records for over 3500 snake species worldwide to ...
