Functional tooth unit, periodontal status, and association with weight change in older adults

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Literature reports that having fewer teeth is associated with reduced chewing capacity, which in turn may lead to weight changes due to diminished oral functionality. This study aims to assess the association between functional tooth units (FTU) and periodontal status and weight change among older adults participating in the Health,

Count data analysis using poisson regression and handling of overdispersion [PDF]

open access: yes, 2009
Count data is very common in various fields such as in biomedical science, public health and marketing. Poisson regression is widely used to analyze count data. It is also appropriate for analyzing rate data.

Overdispersion has little effect on the balanced or minimum error mapping solutions.

open access: yes, 2023
A) Two example cells, one per column. The left cell’s spiking activity does not include overdispersion, the bottom plot shows the variability in the cell’s firing during passes through the place field (black bars; text above gives the standard deviation ...

Marine Isotope Stage 4 glaciation in northern England, UK: Evidence from Victoria Cave, North Yorkshire

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Victoria Cave, north Yorkshire, England, contains a long sequence of Pleistocene clastic sediments and calcite flowstones. Earlier work, using U–Th dating, established that the flowstone units formed in interglacial stages corresponding to Marine Isotope Stages (MIS) 13, 11, 9, 7 and 5.

Analysis of overdispersion in airborne transmission of COVID-19

open access: yes, 2022
Superspreading events and overdispersion are hallmarks of the COVID-19 pandemic. However, the specific roles and influence of established viral and physical factors related to the mechanisms of transmission, on overdispersion, remain unresolved.

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 ...

Community composition mediates interannual shifts in pollinators' roles within networks

open access: yesNordic Journal of Botany, EarlyView.
Plant–pollinator networks are complex structures that describe interactions between plants and pollinators within ecological communities. Understanding how these networks are organized is crucial for the preservation of populations, communities, and ecosystem services, because network structure is linked to the function and resilience of communities ...

Semiparametric estimation of on-stie count data models [PDF]

open access: yes
This article proposes semiparametric estimation of on-site count data models based on a series expansion approach of Gurmu, Rilstone and Stern (1999, Journal of Econometrics 88, 123-150), which is flexible and adaptable for a form of overdispersion as ...
