More than 60%and76%6% of cumulative variance is captured by first two components and first three principal components, respectively.
By Gary Marcus March 12 , 2013 Last week the Human Connectome Project, supported jointly by sixteen components of the National Institutes of Health, released its first set of data, a massive set of structural and functional images of the brains of sixty-eight adult volunteers — to almost no fanfare whatsoever.

One way EHS scholars distinguish risk regulatory programs is by isolating two program components: first, a trigger mechanism that authorizes the agency to act on the basis of an anticipated, but ultimately uncertain, harm; and second, a standard specifying the level or stringency with which it should regulate the harm or the factors it may consider in doing so.
Finally, the receptors that are most central in the plane formed by the first two components are differentiated by the third component (Figure 3A).
Similarly, for 'local within-group PCA' we used same imputation / subsetting procedure, ran PCA on each set, and calculated the share of variance explained by first two components.
A Principal Component Analysis (PCA) of microarray data showed that 72.4% of the observed transcriptional changes were explained by the first two components and 6.2% by the third component.
We also performed a PCA on the expression pattern of genes rather than isoforms and we found that tissues are resolved by the first two components, while genotypes cannot be resolved, even when the second and third components are considered (Additional file 2: Figure S7).
Grouping of VRs by cluster is apparent by the first two components in PCA, as shown by V2RB and V2RC, which are highly conserved among lab-derived strains, and V2RA5, which is highly variable.
