However, in practice, we will find that for any given threshold there is some fraction of false positive and false negative assignments.
As far as DISOPRED3 is concerned, the current results show that most false negative assignments correspond to residues predicted as ordered in the first place.
The intellectual task of determining which codes may be used legitimately with a 'complications' flag may be compared with that of clinical diagnosis: there will be false positive and false negative assignments, as well as accurately positive and negative ones.
In all cases sequence assignments were made conservatively, i.e. sequences were removed if there was no clear reason for their inclusion, favoring a lower rate of false-positive assignment at the expense of a higher false-negative assignment rate.
One point was given for each correct dengue-positive or dengue-negative assignment.
Like most automated data processing procedures, peak picking and alignment steps are prone to false-positive and false-negative assignments, materialized, for instance, by non-extracted true analyte peaks, over-representation of noise-associated features and non-correctly aligned mass features.
The employment of Affect to analyse evaluative language in the English discussions in the pilot study revealed that there were issues with the theorisation of this sub-system of Attitude including (a) the negative polarity assignment of Affect-Insecurity: Surprise, and (b) the typology of Affect types.
There were issues relating to both Affect and Appreciation such as the negative polarity assignment for Surprise, the irrealis and realis trigger basis for the categorisation of Fear under Dis/Inclination (Affect) and the unclear distinction between Impact and Quality in the system of Appreciation.
Therefore, false negative haplogroup assignments cannot be fully excluded.
