Measurement, Models, and Uncertainty
IEEE Transactions on Instrumentation and Measurement, 2012Against the tradition, which has considered measurement able to produce pure data on physical systems, the unavoidable role played by the modeling activity in measurement is increasingly acknowledged, particularly with respect to the evaluation of measurement uncertainty.

Disagreement as a Measure of Uncertainty
Journal of Money, Credit and Banking, 1996This paper presents evidence from the Livingston survey of inflation forecasts that forecaster disagreement provides a useful measure of forecast uncertainty. The evidence is analogous to the evidence for ARCH effects. Disagreement at the time of the forecast has as large positive effect on the conditional variance of the subsequent forecast error.

The Measurement of Uncertainty in Illness
Nursing Research, 1981The purpose of this investigation was to explore the role of uncertainty as a significant variable influencing patients' experiences in illness, treatment, and hospitalization. A theory was proposed on uncertainty in illness. Based upon this conceptualization, a 30-item scale tapping the uncertainty in symptomatology, diagnosis, treatment, relationship

ON THE MEANING AND MEASURE OF UNCERTAINTY
Metroeconomica, 1952Summary§ 1. The additive procedure of numerical probability not applicable to assessment of the merit of a non‐divisible non‐seriable experiment. ‐ § 2. The difficulties of supposing that courses of action are compared by considering amultiplicity of hypotheses about the outcome of each. ‐ § 3.

Measurement uncertainty in the pH measurement procedure
Analytical and Bioanalytical Chemistry, 2002A measured value without even an approximate knowledge of the uncertainty is worthless. The uncertainty is part of every measured value and specification of the uncertainty is part of every analytical procedure. The uncertainty makes the value independent of its origin.

Expanded Uncertainty of a Measurement and an Uncertainty Budget for a Single Measurement
2014This chapter takes the standard uncertainty calculated in the previous chapter and shows how to apply a statistical confidence in order to determine the expanded uncertainty, which is commonly referred to as “the uncertainty of a measurement.” The chapter demonstrates how uncertainties quoted at one level of confidence (e.g., on a calibration ...
