It looks, therefore, like the sign of a previously unknown phenomenon.Of course, some as-yet unidentified error could have been made.
Therefore, the observed bias could be due to (i) unrealistic assumptions (used by the inference method) that might be more violated under in-vitro simulations than in-silico simulation, or (ii) to a systematic, unidentified, error in our implementation of the migration among populations in the laboratory.
Failure of studies due to unidentified error sources and inadequate performance is not only an issue of misspending budgets.
While the reason for this drop remains unclear, potential explanations are unidentified pedigree errors introduced with the additional animals, phenotype mis-specification or due to the limitations of the analysis software with very tightly linked markers.
Other unidentified taxonomic errors may be present within our dataset.
This deficiency alone would be expected to exclude real-time qPCR from a potentially large category of applications, where unidentified quantitative errors cannot be tolerated.
Most notable is the ability to monitor amplification kinetics within individual amplification reactions, providing the capability to reveal sample-specific inhibition that would otherwise generate unidentified quantitative errors.
Unidentified genotyping errors are one possible cause of failure to map markers, both failure to detect significant twopoint linkage and rejecting markers inflating the map.
The big question is whether OPERA researchers have discovered particles going faster than light, or whether they have been misled by an unidentified "systematic error" in their experiment that's making the time look artificially short.
Accuracy was measured by calculating the proportion of all images in each test set that were identified correctly, with images left unidentified treated as errors.
