Hi, does anyone know how to self-define the variance-covariance structure of the within-subject variance for the mixed models , i.g,
yi=Xibeta+Zibi+ei For ei I want to use kronecker product so its variance matrix will be R=V*E, here * represents Kronecker product. Thanks so many. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
