A nominal threshold was applied in order to avoid false negative findings.
A nominal threshold of P < 0.01 was defined to identify genes of potential interest for the EASE analysis.
If no wave was detected at maximum intensity stimulation, a nominal threshold of 110 dB SPL was assigned.
Instead, appropriate sampling and analysis can demonstrate that at that time and location, prevalence was below a nominal detection threshold (Technical Appendix) (17).
Thus, for the resampling analysis we set a nominal p-value threshold for the McDonald-Krietman tests; enrichment is thus defined as having a significantly greater number of McDonald-Krietman tests with p-values below this nominal threshold.
The main advantage is communication: the public would understand what the level of unemployment means, while understanding a nominal GDP threshold would be a struggle.But an unemployment threshold also shows the challenges of targeting a particular level Exhibit 2 below illustrates this.
Dashed line shows a nominal significance threshold of p = 0.01.
For the collapsing and allele-matching methods, a nominal significance threshold was kept at 0.05.
109 of the 684 SNPs surpassing a nominal significance threshold were matched with salmon fry transcriptome data using blastn alignment.
At a nominal p-value threshold of P<0.0001, we would expect 20 false positives at any putative QTL position.
