ICC Estimation

Posted by xinian on 03 Nov 2011 at 16:43 GMT

To avoid negative and get more accurate estimation of sample ICC, the variance components in above linear mixed-effects model (4) were estimated with the restricted maximum likelihood (ReML) approach

Usage of ReML is critical to estimate the sample ICC.
