City Slicker or Country Bumpkin?—Distinguishing Urban and Rural Residents From Subtle Facial Cues

European Journal of Social Psychology, EarlyView.
ABSTRACT Stereotypes characterize urban and rural residents as differing in traits, values and social outcomes. Here, we examined how people's stereotypes about urban and rural residents differ, testing their validity using a lens model. Results showed that participants detected whether people resided in urban or rural areas from photos across three ...

Consistency of Restricted Maximum Likelihood Estimators in High-Dimensional Kernel Linear Mixed-Effects Models with Applications in Estimating Genetic Heritability

Mathematics
Restricted maximum likelihood (REML) estimators are commonly used to obtain unbiased estimators for the variance components in linear mixed models. In modern applications, particularly in genomic studies, the dimension of the design matrix with respect ...

Clustering in Additive Mixed Models with Approximate Dirichlet Process Mixtures using the EM Algorithm [PDF]

, 2013
We consider additive mixed models for longitudinal data with a nonlinear time trend. As random effects distribution an approximate Dirichlet process mixture is proposed that is based on the truncated version of the stick breaking presentation of the ...

A robust DF-REML framework for variance components estimation in genetic studies [PDF]

Bioinformatics, 2017
Abstract Motivation In genetic association studies, linear mixed models (LMMs) are used to test for associations between phenotypes and candidate single nucleotide polymorphisms (SNPs). These same models are also used to estimate heritability, which is central not only to evolutionary biology but also

Are single‐item global rating scales the same, better, or worse than multi‐item scales in epilepsy: A scoping review and meta‐analysis

Epilepsia, EarlyView.
Abstract Objective To examine the performance of single‐item global ratings (SIGRs) and multi‐item scales (MISs) in epilepsy research, and assess the influence of diverse constructs, study designs, and statistical methods. Methods Systematic scoping review following Preferred Reporting Items for Systematic reviews and Meta‐Analyses (PRISMA) and Joanna ...

Parentesco na seleção para produtividade e teores de óleo e proteína em soja via modelos mistos

Pesquisa Agropecuária Brasileira, 2013
O objetivo deste trabalho foi avaliar influência da informação de parentesco na seleção de progênies de soja quanto à produtividade e aos teores de óleo e proteína, com base no uso de modelos mistos de predição dos valores genéticos. Novecentas progênies

Inverse transformed encoding models - A solution to the problem of correlated trial-by-trial parameter estimates in fMRI decoding [PDF]

, 2019
Techniques of multivariate pattern analysis (MVPA) can be used to decode the discrete experimental condition or a continuous modulator variable from measured brain activity during a particular trial. In functional magnetic resonance imaging (fMRI), trial-

Fasting remnant lipoproteins can predict postprandial hyperlipidemia

Lipids in Health and Disease, 2012
Background Hypertriglyceridemia and postprandial hyperlipidemia is thought to play an important role in atherosclerosis, but to select patients at high-risk for cardiovascular diseases is difficult with triglycerides (TG) alone in these patients. Methods

High-dimensional genome-wide association study and misspecified mixed model analysis

, 2014
We study behavior of the restricted maximum likelihood (REML) estimator under a misspecified linear mixed model (LMM) that has received much attention in recent gnome-wide association studies.

Knowledge of obstetric fistulas and associated factors among women of reproductive age in Ethiopia: Systematic review and meta‐analysis

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objectives Obstetric fistula is a complication occurring in childbearing women. It is a major problem in developing countries and results in poor childhood development and limited use of obstetric care. The aim of this study was to show the pooled prevalence of knowledge of obstetric fistulas among reproductive age women.
