[R-sig-ME] Random effect variance = zero

[Marco Plebani]

Dear list members,

Thank you all for the useful feedback.
For reference, here are two other recent threads closely linked to the one discussed here (i.e. https://stat.ethz.ch/pipermail/r-sig-mixed-models/2014q3/022496.html ):
https://stat.ethz.ch/pipermail/r-sig-mixed-models/2014q3/022359.html (“Same variable as both fixed and random”)
https://stat.ethz.ch/pipermail/r-sig-mixed-models/2014q3/022389.html (“Mixed effect models for a study with no (real)	replication”)
They sort of built up to the issue raised by Aurore.

Cheers,

Marco
