mlmmmbd.em {mlmmm} | R Documentation |
Implementation of em.pan() that restricts the covariance matrix for the random effects to be block-diagonal. This function is identical to pan() in every way except that psi is now characterized by a set of r matrices of dimension q x q.

Same as for em.pan() except that the starting value for psi have new dimensions: (q x q x r) |

A list with the same components as that from em.pan(), with a minor difference: the dimension of "psi" is now (q x q x r).
