I want to extract standard deviation of residual from `glmer()` function in R .
So I wrote :
I noticed that the last command `sigma(lmer_obj)` returns always "1" irrespective of data , that is , whether I used `cbpp` data or own simulated data from multilevel logistic distribution , the residual standard error is always 1 .
How can I get the residual standard deviation from `glmer()` function ?
So I wrote :
Code:
lmer_obj = glmer(Y ~ X1 + X2 + (1|Subj), data = D, family = binomial)
sigma(lmer_obj)How can I get the residual standard deviation from `glmer()` function ?
