I am using random intercept logistic model (in lme4) to calculated

Intraclass correlation coefficient (ICC). lme4 only provides point

estimates and standard deviation (not standard errors) of variance

estimates.These

point estimates can be used to calculated point estimates for ICC. The

problem is how can I calculate standard error and confidence interval for

ICC. I couldn't find any literature showing formula to calculate confidence

interval around ICC. Or is it not possible to calculate SE and CI for ICC

due to skewed sampling distribution (Please see PMCID: PMC3426610).

Thanks
