Dear fellow AllStatters,
I am hoping someone can help me. I ammodelling a binary outcome using a
mixed effects model with random intercept for residential neighbourhood in
which my subjects are clustered (nlmer in the lme4 package for R). I nwo
need to "integrate over the neighbourhood random effect" to get a
marginalized estimate [quote from a paper I am reading]. This is beyond my
statistical skills and so I am turning to the list: how do I integrate out
the neighbourhood effects? Does anyone know of an article or a book which
explains why and how to do this? Or can anyone point me to a function or to
code (in SAS or R) for this integration??
Any help would be greatly appreciated.
David (Evans).
