Consider threshold model with single random effect plus error.
On underlying scale, total variance is say B + W and intraclass
correlation is B/(B + W).
Let R = B/W. Total variance is W(1+R) and correlation is R/(1+R). For
probit W = 1, for logit W = pi^2/3, etc.
In asreml output, the same number appears in variance ratio and
component columns. Is this R or B = RW ?
