Understanding the Pattern of Cognitive Decline in GBA1‐Related Parkinson's Disease: An Exploratory Longitudinal Multi‐Cohort Study

open access: yesAnnals of Neurology, EarlyView.
Objective People with Parkinson's disease (PD) who carry a pathogenic GBA1 variant (PDGBA1) are at higher risk of cognitive impairment than those without the variant (PDGBA1_wildtype). To date, little is known about the pattern and evolution of cognitive decline in PDGBA1. This multicenter study characterized the cognitive profile of PDGBA, focusing on

Heterogeneous model for superdiffusive movement of dense core vesicles in C. elegans

open access: yesScientific Reports
Transport of dense core vesicles (DCVs) in neurons is crucial for distributing molecules like neuropeptides and growth factors. We studied the experimental trajectories of dynein-driven directed movement of DCVs in the ALA neuron in C.

An Insurance Type Model for the Health Cost of Cold Housing

open access: yesRevstat Statistical Journal, 2009
This paper introduces a substantive problem, namely the link between fuel poverty and excess winter morbidity amongst older people, and shows how the GAMLSS suite of programs (www.gamlss.com) can be used to provide a very flexible method of modelling ...

FACTORS AFFECTING INDONESIAN PADDY HARVEST FAILURE: A COMPARISON OF BETA REGRESSION, QUASI-BINOMIAL REGRESSION, AND BETA MIXED MODELS

open access: yesBarekeng
The Paddy harvest failure rate is one of the key aspects in determining the total number of claims in a crop insurance policy. It is also an important factor indicating the fulfillment of targeted total production. Therefore, we proposed Beta Regression,

A Statistical Model for Analyzing Interdependent Complex of Plant Pathogens

open access: yesRevista Colombiana de Estadística, 2012
We introduce a new approach for modeling multivariate overdispersed binomial data, from a plant pathogen complex. After recalling some theoretical foundations of generalized linear models (GLMs) and Copula functions, we show how the later can be used to ...

Beta-binomial/gamma-Poisson regression models for repeated counts with random parameters

open access: yes, 2011
Beta-binomial/Poisson models have been used by many authors to model multivariate count data. Lora and Singer [Stat. Med. 27 (2008) 3366-3381] extended such models to accommodate repeated multivariate count data with overdipersion in the binomial ...

Transcriptomic Profiling in Skeletal Muscle Identifies Associations With Knee Osteoarthritis: The Study of Muscle, Mobility and Aging

open access: yesArthritis &Rheumatology, EarlyView.
Objective The association between skeletal muscle gene expression and knee osteoarthritis (OA) was examined among older adult participants of the Study of Muscle, Mobility and Aging (SOMMA). Methods Inclusion criteria included knee radiographs and bulk RNA sequencing in vastus lateralis muscle, resulting in 523 participants (56% female).
