I'm having trouble trying to find the covariance of the random effect of a
lmer output. This result is printed in the console when I call the function; for example if I write:
fm.lmer = lmer(distance ~ I(age-11) + (I(age-11) | Subject), data = Orthodont) fm.lmer
Random effects: Groups Name Variance Std.Dev. Corr Subject (Intercept) 4.55464 2.1342 I(age - 11) 0.05127 0.2264 0.50 Residual 1.71627 1.3101 Number of obs: 108, groups: Subject, 27
but I can not retrieve this result anywhere (even in the
summary of the object).
I have the same problem with the package nlme.
