Analysis of neonatal clinical trials with twin births

open access: yesBMC Medical Research Methodology, 2009
Background In neonatal trials of pre-term or low-birth-weight infants, twins may represent 10–20% of the study sample. Mixed-effects models and generalized estimating equations are common approaches for handling correlated continuous or binary data ...

%QLS SAS Macro: A SAS Macro for Analysis of Correlated Data Using Quasi-Least Squares

open access: yesJournal of Statistical Software, 2010
Quasi-least squares (QLS) is an alternative computational approach for estimation of the correlation parameter in the framework of generalized estimating equations (GEE). QLS overcomes some limitations of GEE that were discussed in Crowder (1995).
