Forcing extra iterations

!EXTRA

!EXTRA n requests an extra mod( n,10) rounds of iteration after apparent convergence. The default for n is 1. This qualifier has lower priority than !MAXIT, ABORTASR.NOW and FINALASR.NOW.

Convergence is judged by changes in the REML log-likelihood value and variance parameters. However, sometimes the variance parameter convergence criteria has not been satisfied.
