It may have many types of sources, from quantifiable errors in the data to ambiguously defined concepts or terminology, or uncertain projections of human behavior.
In view of hundreds of CAT documents per repository, however, it seems unlikely that a human evaluator's attention will not wander, leading to less than optimal scrutiny of the documents and introducing a non-quantifiable error to the evaluation.
However, latent constructs do have quantifiable statistical error parameters, and are not technically "error free".
Some of the problems involved in social measurement include the lack of universally accepted theoretical frameworks and thus of quantifiable measures, sampling errors, problems associated with the intrusion of the measurer on the object being measured, and the subjective nature of the information received from human subjects.
The primary strength of the system is a scientifically rigorous design-based statistical estimation method that produces estimates of forest attributes with known sampling error and quantifiable measurement error.
As quantifiable examples, image recognition error rates have fallen from 42percenttoto just over 5percentt between 2011 and 2014, and the number of AI software projects at Google has climbed from less than 100 in 2012 to more than 2,700 this year.
Accuracy within the defined quantifiable ranges was high (0.1 13 % error) under all conditions in plasma, including those with other toxins expected to be present during infection.
However, the source of this error, which is not quantifiable, is similar in all cases and thus can be considered negligible for the reconstructions and comparisons of the unfolded maps.
Unfortunately, defeaturing inevitably leads to analysis errors that are not easily quantifiable within the current theoretical framework.
Note that, unlike our previous work examining post-error slowing [12], which was a quantifiable behavioral change, a stop success trial did not involve a reaction time.
Compared to the traditional plug assay, the sleek design of angioreactors provides a standardized platform for reproducible and quantifiable in vivo angiogenesis assays and prevents assay errors due to absorption of Matrigel by the mouse.
