search for: sigma2_randomslope

...he intraclass correlation coefficient (ICC) as a measure of concordance of pixel intensity in between left and right Side . Can anybody help me with the correct formula, i.e. do you have to include variance component estimator for level 1 ("Dog"), too? Is it something like this: ICC = (sigma2_RandomSlope-Dog + sigma2_RandomSlope-SidewithinDog) / (sigma2_RandomSlope-Dog + sigma2_RandomSlope-SidewithinDog + sigma2_error) Any hints would be appreciated!
