[R-sig-ME] equation for linear mixed model for repeated measures data

[Thierry Onkelinx]

Dear Ahmad,

You can find that in books like Pinheiro & Bates (2000) or Zuur et al
(2009).

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to say
what the experiment died of. ~ Sir Ronald Aylmer Fisher
The plural of anecdote is not data. ~ Roger Brinner
The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of data.
~ John Tukey
