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.
Differences in women's labour market participation across Canadian provinces have been attributed to variance in infertility rates and accessibility to day care, education and job opportunities.
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.
This data was analyzed with 2-way crossed ANOVA algorithms to derive the components of variance attributed to disagreement between observers, to differences between filmed subjects, and to residual "unexplained" variance.
The AMOVA for K = 3 indicated that 25% of the variance was attributed to variation between the three clusters and that 75% of the variance was due to variation within clusters.
These differences in the kidneys and liver could be attributed to the variances in the clearance and catabolism of the chelates on the Ab conjugate, 225Ac-DOTA chelate vs 111In-DTPA chelate [41].
Hence, the heterogeneity is probably attributed to the variances with regard to features of population, the subtypes of TNBC, the disease stages, the antibody source, the dilution rate, the cut-off value of AR and EGFR expression, and so forth.
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).
