LMM with variance structure at the cluster level was also fitted.
This design differs from that of a crossover study, in that the treatment sequence is allocated at the cluster level.
The best selected model form from step 1 was used to build LMM with random effect at the cluster level.
In addition, the storage mechanism for maximum data availability (also called data replication) brings 100% redundancy at the cluster level.
At the cluster level, a power optimizer is proposed to incrementally consolidate VMs onto the most power-efficient servers on a longer time scale.
SPMt maps were thresholded at uncorrected p < 0.001 at the voxel level combined with a FWE-corrected p < 0.05 at the cluster level.
The current study focuses on the grouping variable at the cluster level, which is consistent with the empirical example introduced later.
Modelling the residual variance at the cluster level by using variance function (varIdent) improved the model performance as measured by the AIC.
To address the issue of multiple comparisons, the statistical maps were thresholded at P < 0.001 (voxel level) and FWE corrected to P < 0.05 at the cluster level.
For all voxel-based analyses, we used an uncorrected p < 0.001 at the voxel level combined with a FWE-corrected p < 0.05 at the cluster level.
Indeed, the intention of the UDF feature developers was to delegate a light treatment at the cluster level on resulted rows.
