Multivariate measures of skewness and kurtosis for skew-elliptical distributions

Communications in Statistics - Theory and Methods
This article examines eight measures of skewness and the Mardia measure of kurtosis for skew-elliptical distributions. Multivariate measures of skewness considered include Mardia, Malkovich-Afifi, Isogai, Song, Balakrishnan-Brito-Quiroz, Móri-Rohatgi-Székely, Kollo, and Srivastava measures.

The decline of 6‐thioguanine nucleotides is not linked to impaired efficacy or safety of thiopurines in pregnant women with inflammatory bowel disease

British Journal of Clinical Pharmacology, EarlyView.
Background Thiopurines are used to maintain remission in inflammatory bowel disease (IBD). These drugs are metabolized into 6‐thioguanine nucleotides (6‐TGN), associated with efficacy, and 6‐methylmercaptopurine ribonucleotides (6‐MMPR), associated with adverse drug reactions. Pregnancy has been linked to a shift in thiopurine metabolism, characterized

Skewness and kurtosis as locally best invariant tests of normality

, 2006
Consider testing normality against a one-parameter family of univariate distributions containing the normal distribution as the boundary, e.g., the family of $t$-distributions or an infinitely divisible family with finite variance.

Mid‐Domain Effect and Wooded Habitat Shape Mediterranean Reptile Communities

Biological Diversity, EarlyView.
Analyzing a large number of reptiles observed across protected areas in Central Italy, we tested whether the mid‐domain effect explains hump‐shaped richness–elevation patterns. Species richness was best predicted by the combined influence of geometric constraints and woodland cover, revealing two contrasting species clusters and offering a robust ...

The influence of rivers on seabird foraging ecology

Biological Reviews, EarlyView.
ABSTRACT Rivers act as vital arteries to the world's oceans, delivering fresh water and nutrients that sustain marine ecosystems. Globally, river flow increasingly is being altered by climate change and anthropogenic pressures; yet the significance of rivers to predatory marine species, such as seabirds, and the extent to which river‐related changes ...

The costs of extra‐pair behaviours in birds

Biological Reviews, EarlyView.
ABSTRACT Extra‐pair behaviours – reproductive behaviours, including those related to copulation and paternity of offspring, amongst animals outside of a social pair bond – have long intrigued behavioural ecologists, particularly from the female animal's perspective.

Sustainability‐Oriented Innovation and Circular Economy Transitions: Evidence From the UK Textile and Clothing Industry

Business Strategy and the Environment, EarlyView.
ABSTRACT The transition to a circular economy (CE) in the textile and clothing (TC) industry is frequently attributed to sustainability‐oriented innovation (SOI), yet empirical understanding of the systemic conditions under which SOI enables CE remains underdeveloped.

Takeover Vulnerability and the Discipline of ESG Overinvestment

Business Strategy and the Environment, EarlyView.
ABSTRACT While takeovers serve a disciplinary role by replacing inefficient managers, the threat of takeovers may compel firms to divert attention from Environmental, Social and Governance (ESG) efforts as a strategic response to external pressure, especially when such firms are already overinvesting in ESG.

Innovation‐Led Sustainability in the Agri‐Food Sector: Evidence From the Global Food and Beverage Industry

Business Strategy and the Environment, EarlyView.
ABSTRACT The agri‐food sector is vital to economic development, but it exerts significant environmental and social pressures. This study draws on the natural resource‐based view. It investigates the strategic sustainability‐performance nexus in the global food and beverage industry using a longitudinal dataset (2013–2023) of 633 firms across the EU ...
