The aim of this work was to characterize particle-size distributions of the saprolite material and use the information obtained to assess between-block variability.
Blocking terms are a common example of random effects where we might be more interested in the estimated magnitude of the block-to-block variability than in the predictions for particular blocks.
However it is worth mentioning in this context that we did not attempt to remove block-to-block variability in the stimulus response, so any that was present was contained in our residual data.
With sAPs blocked, the variability in dAP propagation decreased and shifting of the patterned stimulation appeared no longer to have an effect.
DBL2X polymorphism consists of defined blocks of variability, divided by regions of sequence conservation, a pattern of variation generally observed in PfEMP1 protein domains [14] [16].
Material from non-transgenic and transgenic mice always was imbedded in a single gelatin block to minimalize variability in staining intensity resulting from the sectioning and immunostaining procedure [ 22].
There was no significant effect of stimulation on the number of trials excluded from each block due to variability in response time: no main effect of stimulation [repeated measures ANOVA F 2,24) = 0.291, P = 0.75]; no main effect of time [ F 1,12) = 0.676, P = 0.453]; and no interaction between stimulation and time [ F 2,24) = 1.39, P = 0.67].
Local alignment analysis of these variable blocks revealed that their variability is not due to random mutations on a single consensus sequence.
Variability within a relatively homogeneous block is less than the variability of the entire sample, resulting in a more efficient estimate than without blocking.
The extent of vascular contribution to variability in block and event-related fMRI-BOLD response is not known.
We decided to include rs1876143 as well because, although another polymorphism from its LD block (rs1876140) captured the variability better, the former had a much lower RegulomeDB score.
