Also known as: random effects models, hierarchical linear models, multilevel
models.

Would someone be so kind as to summarize the above or to point me to a
suitable summary of these models?  I gather that these are methods for dealing
with longitudinal data which potentially varies with time and for dealing with
subjects observed at different relative timepoints (or even with missing
data, etc.).

Unfortunately, this all that I gather.  :-)  Any additional illumination would
be most welcome.  Thanks.
