On Ill-Conditioned Generalized Estimating Equations and Toward Unified Biased Estimation [PDF]
, 2000 I address the issue of ill-conditioned regressors within generalized estimating equations (GEEs). In such a setting, standard GEE approaches can have problems with: convergence, large coefficient variances, poor prediction, deflated power of tests, and ...

Efficiency evaluation of quadratic inference functions in the analysis of longitudinal medical data
Russian Open Medical Journal, 2018 Background ― In medical research, longitudinal studies have important and functional roles. Generalized estimating equation (GEE) is used for the analysis of longitudinal and correlated data required to determine the correlation structure among responses.

Generalized Estimating Equations
Methods 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.

Techniques for Estimating Flood-Frequency Discharges for Streams in Iowa, HR-395A, 2001 [PDF]
, 2001 A statewide study was conducted to develop regression equations for estimating flood-frequency discharges for ungaged stream sites in Iowa. Thirty-eight selected basin characteristics were quantified and flood-frequency analyses were computed for ...

Analysis of binary spatial data by quasi-likelihood estimating equations
, 2005 The goal of this paper is to describe the application of quasi-likelihood estimating equations for spatially correlated binary data. In this paper, a logistic function is used to model the marginal probability of binary responses in terms of parameters ...

Longitudinal data methods for evaluating genome-by-epigenome interactions in families
BMC Genetics, 2018 Background Longitudinal measurement is commonly employed in health research and provides numerous benefits for understanding disease and trait progression over time. More broadly, it allows for proper treatment of correlated responses within clusters. We
