-**REMLF90** uses EM REML. For most problems it is the most reliable algorithm but can take hundreds of rounds of iteration. REMLF90 was found to have problems converging with random regression models. In this case, using parameter files that are too lare tan too small usually helps.+**REMLF90** uses EM REML.

 **AIREMLF90** usually converges much faster but sometimes does not converge. Very slow convergence usually indicates that the model is over parameterized and there is insufficient information to estimate some variances. **AIREMLF90** usually converges much faster but sometimes does not converge.
