• Systematic error — Systematic errors are biases in measurement which lead to the situation where the mean of many separate measurements differs significantly from the actual value of the measured attribute. All measurements are prone to systematic errors, often of… …   Wikipedia

• Systematic bias — In metrology, dynamical systems theory, computational mechanics, and statistics, a systematic bias is a bias of a measurement system or estimate method, which leads to systematic errors, namely produces readings or results which are consistently… …   Wikipedia

• Systematic code — In coding theory, a systematic code is one in which the input data are embedded in the encoded output. Similarly, a non systematic code is one in which the output does not contain the input bits. Such codes are used to add redundant information… …   Wikipedia

• Type I and type II errors — In statistics, the terms Type I error (also, α error, or false positive) and type II error (β error, or a false negative) are used to describe possible errors made in a statistical decision process. In 1928, Jerzy Neyman (1894 1981) and Egon… …   Wikipedia

• Memory errors — Memory gaps and errors refer to the incorrect recall, or complete loss, of information in the memory system for a specific detail and/or event. Memory errors may include remembering events that never occurred, or remembering them differently from …   Wikipedia

• Data Validation and Reconciliation — Industrial process data validation and reconciliation or short data validation and reconciliation (DVR) is a technology which is using process information and mathematical methods in order to automatically correct measurements in industrial… …   Wikipedia

• Measurement uncertainty — In metrology, measurement uncertainty is a non negative parameter characterizing the dispersion of the values attributed to a measured quantity. The uncertainty has a probabilistic basis and reflects incomplete knowledge of the quantity. All… …   Wikipedia

• Random error — Random errors are errors in measurement that lead to measurable values being inconsistent when repeated measures of a constant attribute or quantity are taken. The word random indicates that they are inherently unpredictable, and have null… …   Wikipedia

• Scattering parameters — or S parameters are properties used in electrical engineering, electronics engineering, and communication systems engineering describing the electrical behavior of linear electrical networks when undergoing various steady state stimuli by small… …   Wikipedia
