FYI I ran the crossed models:

xtmixed Score, || _all: R.Rator, covariance(identity) || Application:,
covariance(independent) reml variance

xtmixed Score if Rator != 4, || _all: R.Rator, covariance(identity) ||
Application:, covariance(independent) reml variance

And got ICC estimates of 0.61 and 0.22, respectively, which are
essentially the same as for the fixed effects on Application model,
which isn't surprising. The clear difference between the crossed and
random intercept model will be on the interval estimate, but that's
not available here because estat icc doesn't work.
