Generalized Estimating Equations

open access: yesMethods of Information in Medicine, 2010
Summary Background: Generalized estimating equations (GEE) are an extension of generalized linear models (GLM) in that they allow adjusting for correlations between observations. A major strength of GEE is that they do not require the correct specification of the multivariate distribution but only of the mean structure.

Multicollinearity and Linear Predictor Link Function Problems in Regression Modelling of Longitudinal Data

open access: yesMathematics, 2023
In the longitudinal data analysis we integrate flexible linear predictor link function and high-correlated predictor variables. Our approach uses B-splines for non-parametric part in the linear predictor component.

Grouped Generalized Estimating Equations for Longitudinal Data Analysis

open access: yesBiometrics, 2022
Abstract Generalized estimating equation (GEE) is widely adopted for regression modeling for longitudinal data, taking account of potential correlations within the same subjects. Although the standard GEE assumes common regression coefficients among all the subjects, such an assumption may not be realistic when there is potential ...

Pathway analysis of rare variants for the clustered phenotypes by using hierarchical structured components analysis

open access: yesBMC Medical Genomics, 2019
Backgrounds Recent large-scale genetic studies often involve clustered phenotypes such as repeated measurements. Compared to a series of univariate analyses of single phenotypes, an analysis of clustered phenotypes can be useful for substantially ...

Factors associated with mortality from tuberculosis in Iran: an application of a generalized estimating equation-based zero-inflated negative binomial model to national registry data [PDF]

open access: yesEpidemiology and Health, 2019
OBJECTIVES Tuberculosis (TB) is a global public health problem that causes morbidity and mortality in millions of people per year. The purpose of this study was to examine the relationship of potential risk factors with TB mortality in Iran. METHODS This
