Constraints On Random Effects: Example and Test
###############################################

This example demonstrates
:ref:`problem@Maximum Likelihood@Random Constraints` .
To be specific, it demonstrates a case where the constraints ensure
that the sum of the
:ref:`optional random effects<problem@Notation@Optimal Random Effects, u^(theta)>`
is zero.
In addition, for the same case without the constraint,
the optimal random effects do not satisfy this condition.
