Observational error (or measurement error) is the difference between a measured value of a quantity and its unknown true value. Such errors are inherent...

errors of the measurement procedure; it indicates a confidence level in the measurement. Errors are evaluated by methodically repeating measurements and...

In statistics, errors-in-variables models or measurement error models are regression models that account for measurement errors in the independent variables...

flawed experiment. Eliminating the systematic error improves accuracy but does not change precision. A measurement system is considered valid if it is both...

a variety of reasons, among them a computing machine precision or measurement error (e.g. the length of a piece of paper is 4.53 cm but the ruler only...

The notation for standard error can be any one of SE, SEM (for standard error of measurement or mean), or SE. Standard errors provide simple measures of...

Cosine error is a type of measurement error caused by the difference between the intended and actual directions in which a measurement is taken. Depending...

be due to a variability in the measurement, an indication of novel data, or it may be the result of experimental error; the latter are sometimes excluded...

x_{i}=x_{i}^{*}+\nu _{i}} where ν i {\displaystyle \nu _{i}} is the measurement error or "noise". In this case, a model given by y i = α + β x i ∗ + ε i...

account. Correlation can arise from two different sources. First, the measurement errors may be correlated. Second, when the underlying values are correlated...

x, and estimating the slope of the line. Statistical variability, measurement error or random noise in the y variable causes uncertainty in the estimated...

time to calculate velocity and position (see dead reckoning), any measurement errors, however small, are accumulated over time. This leads to 'drift':...

captured by a construct in relation to the amount of variance due to measurement error. The average variance extracted was first proposed by Fornell & Larcker...

nonsampling errors into five general sources or types: specification error, frame error, nonresponse error, measurement error, and processing error. Specification...

portion of the model incorporated measurement errors which permitted measurement-error-adjustment, though not necessarily error-free estimation, of effects...

Measurement errors can be categorized into two basic types: random errors due to intrinsic sensor accuracy and systematic errors (or gross errors) due...

There is substantial measurement error with many breast volume measures, but MRI imaging appears to have among the lowest error and hence to be the most...

engineering to specify the error propagation as a mathematical effect of navigation satellite geometry on positional measurement precision. Bad DOP vs Good...

measurements". In November, OPERA published refined results where they noted their chances of being wrong as even less, thus tightening their error bounds...

to understand the implications of measurement error for decisions made about a product or process. Proper measurement system analysis is critical for producing...
