I get an output from a glmer package, but would like to extract the variance of the Random effects, in this case called trtpair and the value is 0.
Can I extract it directly or do I need to do some further calculations on the "mer" object to get it?
Generalized linear mixed model fit by the Laplace approximation
Formula: cbind(fednmadat$events, fednmadat$patnums - fednmadat$events) ~ treat + tn + (1 | trtpair)
AIC BIC logLik deviance
84.01 153.1 -9.006 18.01
Groups Name Variance Std.Dev.
trtpair (Intercept) 0 0
Number of obs: 60, groups: trtpair, 3
