Does anybody can help me in identifying the error(s) in these code please?
Dear R-user:
Could you please tell me how to extract gradient and Hessian from the following
example model of lmer2 package?
(fm1 <- lmer(Reaction ~ Days + (Days|Subject), sleepstudy))
I would really appreciate your kind help.

Hello EVERYONE,
I need an URGENT help from you please!
How can I see the "estfun" (empirical estimating function) and "df" (degree of
freedom) from the following mixed-model please?
(fm1 <- lmer2(Reaction ~ Days + (Days|Subject), sleepstudy))
Many thanks in advance for your kind help.

Dear R-Users:
I am trying to find the robust (or sandwich) estimates of the standard error of
fixed effects parameter estimates using the package "lmer2". In model-1, I used
"robust=TRUE" on the other, in model-2, I used "robust=FALSE". Both models
giving me the same estimates. So my question i
