Random intercept in residual variance estimate

[RPorneso]

Hi, thanks for developing this really nice and efficient tool!

My question is about outputting the estimated random effects and their covariance. I see in the tutorial that by default a random intercept in the variance is modelled and there is no way to remove that parameter. I noticed, however, that the null model output file does not contain the estimates for random intercept in the variance and the covariance of, in my case, random intercept in the mean and random intercept in the variance. I was wondering if that is an indication that there was no random intercept in the variance that was fitted? Here is the null output file for reference:

Thanks in advance,

Ralph
