2], the magnitude of measurement error
was well within the bounds of the Kuha criterion [[[beta].
Since all tools have error claims based on a certainty or probability of detection that must be accounted for, minimum detection limits and standard deviation measurements taken in infinite combinations ensure that a measured monitoring defect, plus the measurement error
, do not reach or exceed critical defect sizes.
Understanding the nature of random and systemic measurement error
and quantifying the estimates of bias and uncertainty will be critical to developing the objective evidence and communicating the confidence required for achieving the laboratory's quality claims for a single reportable result.
For later data vintages, the measurement error
of the OECD data declines, as the data get closer to their "ex post vintage.
In contrast to NEFSC (2), measurement error
parameters were obtained from experiments and not estimated in the CASA model itself.
J, there are three plausible interpretations; either the discrepancy is due to a structural break or a serious measurement error
, or a combination of both at T.
We find this leads to a more parsimonious state-space representation and a cleaner distinction between various aspects of measurement error
Our findings indicate that the level of task coherence alone has no effect on measurement error
These three pedometers were checked to confirm that the magnitude of measurement error
was below 3% under 1000 steps of usual walking, before all experiments.
We use this case example to: (1) demonstrate how and why ignoring measurement error
can result in large bias in estimating the prevalence of an outcome; and (2) outline some ways to recognize and avoid such bias in future work.
The new PRS05 solution maintains a measurement error
of less than 5% over the full working temperature range.
A specimen guidance system is said to minimize any measurement error
and variance, and in addition, the test results are said to be largely unaffected by frictional forces, due to the use of friction-free ball guides in the fixture.
