Representation in the full data set is biased, so such simple random subsets are biased as well.
Coulombic and Lennard-Jones interaction energies were calculated on a 2 Å rectilinear grid extending 4 Å beyond the edge of any molecule in the full data set.
In the full data collection mode, the robot moves and stops at prescribed increments, typically 30 to 60 cm, and deploys the sensor arrays to collect the data.
This appears as a fundamental paradox: in the full data headache frequency for CM increases over time while comparisons between pairs of waves suggest that headache frequency decreases for CM.
The statistics in Table 4 suggest that the subsample provides a good approximation to the full sample in reproducing approximately the same between-country correlation observed in the full data.
Our main findings show that by sorting specimens from just a subset of the ant genera we retrieved most of the information existing in the full data set, even though the amount of work involved in ant sorting was reduced by about 50%.
Nonetheless, the overall trend is similar to that in the full data set.
Furthermore, we required that at least 90% of the 10,000 base pairs downstream of the SNP have a minimum coverage of 8 in the full data set.
Spatial factors were dummy variables representing the cluster of sites formed at different distances and, in the full data set, distance north from the southernmost site.
Therefore, this limited phylogeny properly represents the evolutionary relationships and divergence of Australian rodent genera and is representative of phylogenetic correlations in the full data set.
For each gene, we computed the fraction of the DTF reads in the full data set that occur in that gene, and divided this by the fraction of the SFT reads in the full data set that occur in that gene.
