A larger amount of variance can be attributed to variance across origin groups: 20% of all variance in the educational achievement of migrant pupils can be attributed to the countries migrant children migrated from.
This pattern was also evident in a hierarchical AMOVA, which showed that only 0.03% of total genetic variance (FCT = 0.0003) could be attributed to variance among sampling locations.
As mentioned above, these differences may be attributed to variance in psychological autopsy methodologies between countries, or yet, to important differences in the prevalence of psychiatric disorders.
Failure to amplify domains from a fraction of the patient samples (241 for eba-175; 124 for msp-3, and 341 for ama-1) was attributed to variance in parasitemia, quality of the filter paper used, and extraction efficiency from the paper.
As most previous reports of default network deactivations were also based on group-level analyses, the amount and source of variability across subjects are not well understood (although some variance has been attributed to the types of cognitive processes that occur spontaneously during periods of rest).
Part of this variance has been attributed to differences within the dopamine (DA) and the serotonin (5HT) systems (Jocham & Ullsperger, 2009).
These differences were attributed to the variance in the pressure and flow distributions from the different facilities and across ventilated and natural supercavitation.
The spatial difference of susceptibility classes can be attributed to the variance of procedure [subjective (AHP) and objective (FR)] in weighting the factors and their classes whereas, the spatial similarity of the susceptibility zones may have occurred due to the use of similar causal factors and the landslide inventory data for both the modeling methods.
However, when considered as two populations containing a number of sub-populations, 11% of the total variation could be attributed to the variance between the regions, while only 4% was attributed to the variation among populations (Table 3).
Specifically, if CMRO2 measures were not consistent across the 3 sessions, weak CMRO2 behaviour associations would not be meaningful, and reliable effects could not be attributed to individual variance, but rather to rapidly changing transient states occurring in one run but not another.
