When applied to a sample, this procedure brings the signals corresponding to SOMAmers in the normalization set closer to the median values across the assay, and reduces the observed variation between replicate samples for all SOMAmers.
If the true ancestor has gone extinct or has not been sampled, this procedure overestimates the age of the lineage.
Using Monte Carlo sampling, this procedure is repeated multiple times to generate sets of possible (SN and SP) combinations.
As each subsample is a random sample with replacement from the full sample, this procedure performs well in the selection of classifiers even when there is over fitting [ 49].
In a nested case-control study where controls are selected using incidence density sampling, this procedure estimates the incidence rate ratio which, given the rarity of the disease, is roughly equal to the odds ratio.
About 15% of nerve samples were sampled using this procedure.
We used a two-position sample shuttle to alternate between the unlabeled sample and labeled sample positions; this procedure substantially decreases the spectral contribution of residual water vapor after subtraction.
The analysis of fluoride in 20 table salt samples using this procedure showed lower values of analyte content than those expected according to the manufacturers' specifications and revealed that the amount of fluoride measured varied significantly in many cases.
Finally, Section 4.3 introduces a flexible formula to compute an adequate number of bootstrap samples, if this procedure is required.
It also demonstrated that average recovery for 30 PM2.5 samples using this procedure was 88% (y = 1.22 × x; r = 0.724; n = 30).
