For REML we need to click the Options button in the dialogue box to ensure that the items 'Model', 'Variance components', 'Estimated effects', 'Stratum variances', 'Deviance' and 'Wald Tests' are included for display; we also need to ensure that the 'Fisher scoring method' is clicked for the 'Optimisation method' as this is necessary for calculating stratum variances.
