A Bimodal Extension of the Beta-Binomial Distribution with Applications

open access: yesAxioms
In this paper, we propose an alternative distribution to model count data exhibiting uni/bimodality. It arises as a weighted version of the beta-binomial distribution, which is defined by a parametric weight function that admits up to two modes for the ...

Second‐Order Between‐Supplier Learning

open access: yesJournal of Operations Management, EarlyView.
ABSTRACT Substantial empirical evidence shows that suppliers in emerging economies can enhance their technological capabilities through direct learning from technologically advanced foreign competitors. However, suppliers in emerging markets may struggle to learn directly from knowledge about competitors’ products that are not widely available on the ...

Factors influencing tooth loss over 9–11 years in young individuals with periodontitis

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Herein, we aimed to identify factors associated with tooth loss over a 9‐ to 11‐year period in young individuals with periodontitis, with a specific focus on the impact of patient compliance. The secondary outcome was to identify factors associated with discontinuation of active periodontal treatment.

What is “accuracy”? Rethinking machine learning classifier performance metrics for highly imbalanced, high variance, zero‐inflated species count data

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Machine learning has opened the door for the automated sorting (classification) of images, holograms and acoustic backscatters of individual plankton, invertebrates, fish and marine mammals. However, this field is complicated by decades of paradoxically promising reports of classifier performance that do not correlate with real‐world uptake of

Comparative Analysis of the Incidence, Prevalence, and Survival of 8 Types of Parkinsonism in a Population‐Based Study with 367 Million Person Years of Observation over 21 Years

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Findings are contradictory regarding changes in the incidence and prevalence of Parkinson's disease (PD) over time; data for other parkinsonian disorders are rare. Objectives To analyze temporal trends in the incidence and prevalence of eight parkinsonisms (PD, MSA, PSP, CBS, DLB, vascular parkinsonism, drug‐induced parkinsonism ...

Association between serum bicarbonate and low mid‐upper arm circumference in patients with non‐dialysis‐dependent chronic kidney disease: A cross‐sectional study

open access: yesNutrition in Clinical Practice, EarlyView.
Abstract Background Although previous experimental studies showed that metabolic acidosis promoted muscle catabolism and impaired protein synthesis, few epidemiological studies reported an independent association between serum bicarbonate levels and muscle atrophy in patients with chronic kidney disease (CKD).

Hierarchical Generalized Linear Models: The R Package HGLMMM

open access: yesJournal of Statistical Software, 2011
The R package HGLMMM has been developed to fit generalized linear models with random effects using the h-likelihood approach. The response variable is allowed to follow a binomial, Poisson, Gaussian or gamma distribution.

Ecosystem size reverses the effect of the spatial coupling between autotrophic and heterotrophic ecosystems

open access: yesOikos, EarlyView.
The flow of non‐living resources between autotrophic and heterotrophic ecosystems can impact their ecosystem function. However, ecosystem size is similarly known to influence ecological properties and it is uncertain how the size of coupled ecosystems mediates the effect of resource flows.
