[R-sig-ME] observation level random effects/kinship model

[Juliet Hannah]

All,

I was reading the following post:

https://stat.ethz.ch/pipermail/r-sig-mixed-models/2011q1/005184.html

which discusses why an observation-level random effect does not make
sense in the linear mixed model
case.

Does anyone know of any references that discuss this?

And for the genetics folks out there, isn't this what the kinship
model is: an observation-level random effect
that is correlated by degree of relatedness?

Thanks,

Juliet Hannah
