Measurement uncertainty, as described in ISO/IEC Guide 98, is a “parameter, associated with the result of a measurement, [which] characterizes the dispersion of values that could reasonably be ...
Bayesian uncertainty analysis represents a powerful statistical framework that integrates prior knowledge with observed measurement data to quantify uncertainty in a consistent probabilistic manner.
A reliable assessment of measurement uncertainty in calibration services is an essential qualitative requirement for any calibration laboratory. While general guidance on the estimation of measurement ...
System-wide measurements of gene expression by DNA microarray and, more recently, RNA-sequencing strategies have become de facto tools of modern biology and have led to deep understanding of ...
Key to that notion of expression is that the signal sent MUST reflect the user’s preference, not the choice of some vendor, institution, site, or network-imposed mechanism outside the user’s control; this applies equally to both the general preference and exceptions.
Accuracy is a desirable aspect which is conceptually well defined. There are some definitions available for ‘accurate measurement’ in the ISO vocabulary of metrology terms. According to them, a ...
Precision can be defined as the closeness in agreement of results during a series of repeat measurements under presumed identical conditions. These results are often expressed as a standard deviation.
In the first round of testing, involving 60 measurements (six samples x five repeat tests x two rounds), an initial review of the results indicated that one sample consistently performed better than ...
Let me start with a great analogy of experimental uncertainty. This is a diagram of the allegory of the cave from Plato. The basic idea of the cave is that people are in a cave (duh) looking at ...
