Measurement error

Errors in measuring an explanatory variable in a regression, which leads to biases in estimated parameters.

Measurement Error

The difference between the value of some quantity and the value obtained by measuring it. It is nearly impossible to attain accurate measurements all the time, especially when one uses a single means of calculation. For this reason, when measuring the value of a company or asset, many analysts will check and double-check their work, and perhaps calculate the value using a different method, in order to ensure accuracy.

It is relatively inexpensive to measure the alcohol content of wine reasonably precisely, although some of the devices used may entail larger measurement errors.
Moreover, these measurement errors are correlated: If potential output is overestimated, then the natural rate is overestimated, and the output gap is underestimated.
We identified this gap and consequently developed LW Finder to determine optimal strain gauge placement and predict measurement errors to dramatically improve the quality of the measured data.
Assumptions of statistical distributions of measurement errors may be invalid if the NDE tool has a significant bias error.
Galvanic three-port isolation, a standard feature of Knick products, ensures reliable isolation of input, output, and auxiliary power supply potentials, which prevents measurement errors or distortion.
It must, however, be noted that the relative effect of the principal components on overall variability tends to be overestimated, since the PCA does not take the dependency of the measurement errors into account in determining the parameters used.
The EMX-4250 has been designed to address challenging precision data-acquisition applications with aggressive anti-aliasing filtering integrated into the front end that helps eliminate unwanted signals and reduce measurement errors.
After the individual calibration, the measurement errors decreased several times.
In production applications, such as color measurements for quality control, the combination of speed, sensitivity and throughput help to reduce measurement errors and ensure accuracy.
The reason for the large measurement errors is lack of a proper standard spectral-responsivity function for the UV meters.
