The authors advocate the use of the generalized variance of the sample means-the determinant of the variance-covariance matrix $D(\overline{y})$ of the means-as a ...

The approach of generalized estimating equations (GEE) is based on the framework of generalized linear models but allows for specification of a working matrix for modeling within-subject correlations.

Multivariate analyses using nonimaging and neuroimaging delivered a more accurate characterization of the link between brain variations and psychosis, demonstrating that general intelligence, BMI, ...
