Survival with Random Effect

open access: yesMathematics, 2022
The article focuses on mortality models with a random effect applied in order to evaluate human mortality more precisely. Such models are called frailty or Cox models.

Fixed-effect versus random-effect model in meta-analysis: How to decide? [PDF]

open access: yesIndian J Anaesth
Interpretation of meta-analysis requires an appropriate understanding of its statistical methods. Data synthesis methods are the basis of the meta-analytic process, and a thorough knowledge of the models used is essential.

Multiple QTL Mapping in Autopolyploids: A Random-Effect Model Approach with Application in a Hexaploid Sweetpotato Full-Sib Population. [PDF]

open access: yesGenetics, 2020
Genetic analysis in autopolyploids is a very complicated subject due to the enormous number of genotypes at a locus that needs to be considered. For instance, the number of... In developing countries, the sweetpotato, Ipomoea batatas (L.) Lam. (2n=6x=90),

Exact inference for the random-effect model for meta-analyses with rare events. [PDF]

open access: yesStat Med, 2020
Meta‐analysis allows for the aggregation of results from multiple studies to improve statistical inference for the parameter of interest. In recent years, random‐effect meta‐analysis has been employed to synthesize estimates of incidence rates of adverse

Iterative Usage of Fixed and Random Effect Models for Powerful and Efficient Genome-Wide Association Studies. [PDF]

open access: yesPLoS Genet, 2016
False positives in a Genome-Wide Association Study (GWAS) can be effectively controlled by a fixed effect and random effect Mixed Linear Model (MLM) that incorporates population structure and kinship among individuals to adjust association tests on ...

RADAR: differential analysis of MeRIP-seq data with a random effect model. [PDF]

open access: yesGenome Biol, 2019
Epitranscriptome profiling using MeRIP-seq is a powerful technique for in vivo functional studies of reversible RNA modifications. We develop RADAR, a comprehensive analytical tool for detecting differentially methylated loci in MeRIP-seq data.

Modeling Heterogeneity in the Genetic Architecture of Ethnically Diverse Groups Using Random Effect Interaction Models. [PDF]

open access: yesGenetics, 2019
In humans, most genome-wide association studies have been conducted using data from Caucasians and many of the reported findings have not replicated in other populations.

Mixture Random-Effect IRT Models for Controlling Extreme Response Style on Rating Scales. [PDF]

open access: yesFront Psychol, 2016
Respondents are often requested to provide a response to Likert-type or rating-scale items during the assessment of attitude, interest, and personality to measure a variety of latent traits.

The quest for the best: The impact of different EPI sequences on the sensitivity of random effect fMRI group analyses. [PDF]

open access: yesNeuroimage, 2016
We compared the sensitivity of standard single-shot 2D echo planar imaging (EPI) to three advanced EPI sequences, i.e., 2D multi-echo EPI, 3D high resolution EPI and 3D dual-echo fast EPI in fixed effect and random effects group level fMRI analyses at 3 ...
