This was achieved by computing a mean value for volumetric silt and clay content (fine sediments) and sand content and coarse fragments (coarse sediments) at depth of 0 200 cm, and then determining which was dominant in a grid cell using a conditional expression in ArcMap Raster Calculator.
An overall analysis of the variation in outcome between the three usage groups was done by computing a P value for each analysis.
In addition to identifying hubs, we also sought out bridge nodes by computing a betweenness value for each node in the illicit-extended drug-target network.
This is done by computing a singular value decomposition (SVD) of V (which requires O(m r) operations) and declaring that the rank of V is equal to the number of singular values that are larger than a predefined threshold ε th (e.g., ε th =0.1).
We assessed the statistical significance of the differential expression of genes by computing a q-value (i.e. minimum FDR) for each gene (Table 1).
The enrichment of essential-essential protein interactions in a network was evaluated by computing a P-value, via calculation of a Z-score and assuming a normal distribution, for the difference between the actual number and the average obtained from randomly selecting proteins to be essential.
Tissue specificity of a given gene is thereby evaluated by computing a P-value reflecting the overrepresentation of ESTs from a tissue among all ESTs of a given cluster (see Supplementary Material and Gupta et al., 2005 for details).
In all cases, statistically significant GO term enrichments were shown by computing a p-value using the hypergeometric distribution (the background set of genes was 6241, the number of ORFs measured in microarray experiments).
This is achieved by computing an encrypted value,, which shows the relation between (acute {d}) and r mod2 ℓ.
The hypothesis that the illuminant could be estimated by computing an average value for the light received as a stimulus has a long history, being proposed, additionally, by Edwin Land [8].
