The choice of thresholds at intermediate levels will be dictated by the nature of the experiment and the required stringency that can be deduced from the ROC table.
This p-value cut-off balances the requirement for stringency that will enrich for selection of true hits and lenience to ensure enough SNPs are included to allow a reasonably accurate measure of the Bayes Factor.
In the standard CRISPR-Cas9 system, the reduced sequence recognition stringency that is observed might come from the evolutionary advantage of an adaptive acquired immune system: a less stringent Cas9 endonuclease that tolerates some mismatches between the crRNA and an evolving invading genome may have been selectively preserved through evolution (Carroll, 2013).
These genes passed the Student's t-test at the threshold of 0.05 and the associative t-test at the threshold of 0.0005, a stringency that results in the selection of less than one expected false positive and less than one expected false negative determination.
Among the approximately 1,300 genes assessed at the higher stringency (that of a 2-standard deviation change in TRAIL-induced caspase-3/7 activity), these RNAi screens did not identify positive regulators of TRAIL.
After the initial screening of probes, the next step is to select a combination of probe length, probe position and assay stringency that fulfill the criteria for assigning a genotype for each mutation site.
Its governor, the peppery Leszek Balcerowicz, may be no loss to diplomacy, but he epitomises the radical economic reform and financial stringency that lies behind Poland's hearty economic growth.
Though he doesn't observe Jewish ritual law with the same stringency that he did when he was a child, he still identifies with Orthodox Judaism.
Spencer's "liberal" utilitarianism, however, differs from Mill's in several respects, including principally the greater stringency that Spencer ascribed to moral rights.
On the other side of the coin, though, poaching inflicts significant costs on many universities, especially public institutions struggling with financial stringency, that lose researchers.
