measurement error

The difference between the true value of something being measured and the value obtained by measurement. Measurement error can be the result of one or more of several different factors, including operational blunders, random error, and systematic error. See: bias; proportional error; random error

Quantum Volume is a measurement, a procedure developed by IBM, that determines how powerful a quantum computer is, accounting for both gate and measurement errors, device cross talk, as well as device connectivity and circuit compiler efficiency.
The results show that temperature measurement errors of sensors A, B, D2 and C were within acceptable ranges and mostly within the accuracies claimed by the manufacturers.
Models of the periodic and aperiodic errors are established in MATLAB using the above values, and the model parameters are calculated and then sent to the error compensation model to achieve dynamic compensation of measurement errors.
HDM and its modifications all require calculation of the ratio of [[Hb].sub.b] values at various time points compared to an initial [[Hb].sub.b] determination; however, the effect of measurement errors on the accuracy of these volume determinations has never been adequately explored.

Moreover, these measurement errors are correlated: If potential output is overestimated, then the natural rate is overestimated, and the output gap is underestimated.
The goal in these traditional RAIM operating environments has been to eliminate large measurement errors due to, for example, satellite clock or ephemeris failures, which can be caused by failures in the satellite or in the control segment.
