to the correlated residual variance structure in Eqn 8.7. As mentioned earlier, residual
error structure is block diagonal with all elements between the various block diagonals
being zero. Thus for the example data in Table 8.1, with n = 3, the R block diagonal
structure for one group is:
é1 r r ù æ10 2 . 0 2 . ö

The MME can then easily be set following the usual principles.
