I must have missed something. From Bill's argument I
see how this is true if you have few observation
within clinic (for example 4), but I am not sure if
the same holds if you have 4 clinics each with 200+
observations which is the most ususal scenario.

Thank you Dr. Gould, I really appreciate you taking
time to answer my question.
