Finally, we had few occurrences in which Dig would crash with unclear errors.
Participants were instructed by a trained investigator [BBA], who also reviewed all food records with each participant to address unclear descriptions, errors, omissions, or doubtful entries.
Additional information from corresponding authors of the included studies will be requested in circumstances where the published data are unclear, contain errors, are missing or require further clarification.
Moreover, it is unclear what the error bars in this figure represent (and, more generally, the authors need to be careful to describe what error bars represent in all of the different graphs in the figures).
It was unclear whether the error affected all models of the iPhone or only the latest version, iPhone 4. The technology blog Engadget said the error probably affected all customers with the latest iPhone 4 software.
Moreover, it is unclear whether the error model does accommodate real behaviour sufficiently well, and if not, it is hard to interpret the results.
Furthermore, it is unclear whether the error rates could be reduced by collecting adequate amounts of training (or adaptation) data or whether novel processing methods have to be developed.
In cases where the quantification of the stimulus or observation was unclear an augmented error of 20% 100% was applied to compensate for the added uncertainty.
Currently, it is unclear how statistical error, uncertainty, and variability are captured and expressed within the bioaccumulation databases described above.
In these cases, it is unclear whether the error is in transferring and/or translating the elements of the character matrix to the tree, students do not understand the concept of a synapomorphy, or students simply do not know they are being asked to map traits parsimoniously.
