These distributions incorporate the best-known estimates for origination dates of these taxa, but are wide enough to allow for shifts in dates that may reflect errors due to interpretation or incompleteness of the fossil record.
Poor credit may reflect errors on credit reports, as it did in Emmett Pinkston's case, or factors such as medical debt, a messy divorce, predatory lending, or simply unemployment.
This could be an effect of amelioration or may reflect errors in the prediction so the results should be interpreted with caution.
The unmappable reads may reflect errors specific to certain sequencing kits (Mortazavi, personal communication, 2009) as well as artefacts from the processing of RNA for massive parallel sequencing (Blow, 2009).
Estimates of rate variation derived from empirical data in plethodontid salamanders were less than those derived from comparable datasets simulated under an enforced molecular clock, suggesting that the empirically-estimated rate variation may reflect error rather than true differences in the underlying biological substitution process.
When the underlying measure is imperfect, marginal improvements from 96%to99%9% may reflect error in measurement and denominator management more than nearly perfectly reliable performance.
This has raised questions about the link between operculum activity and grammatical computations, and suggests that it may reflect error detection and reanalysis instead [Caplan, 2007], consistent with the association found between the FOP activity and the decision-making aspects of auditory perception [Binder et al., 2004].
As denoted in our earlier study this may reflect disease-dependent changes in presystemic bioavailability or may simply reflect errors in parameter estimation using a population-based pharmacokinetic approach.
However, errors in urine collections cannot be fully accounted for because extremely low or high values of the CER may reflect collection errors but may also reflect extremes in body composition.
A few of these changes may reflect sequencing errors, since they come from draft genome sequences, but many of the mutations are shared among phylogenetic closely related species strongly suggesting that these are true evolutionary changes.
