Absolute probability judgement — is a technique used in the field of human reliability assessment (HRA), for the purposes of evaluating the probability of a human error occurring throughout the completion of a specific task. From such analyses measures can then be taken to… … Wikipedia
mean absolute deviation — MAD A measure of forecast error, for example when carrying out adaptive exponential smoothing of time series data. MAD is the average forecast error, either positive or negative, calculated as the sum of the absolute value of forecast error for… … Big dictionary of business and management
Absolute molar mass — is a process to determine the characteristics of molecules. TOC History The first absolute measurements (i.e. made without reference to standards) were based on fundamental physical characteristics and their relation to the molar mass. The most… … Wikipedia
Absolute deviation — In statistics, the absolute deviation of an element of a data set is the absolute difference between that element and a given point. Typically the point from which the deviation is measured is a measure of central tendency, most often the median… … Wikipedia
Approximation error — The approximation error in some data is the discrepancy between an exact value and some approximation to it. An approximation error can occur because the measurement of the data is not precise due to the instruments. (e.g., the accurate reading… … Wikipedia
Mean absolute percentage error — (MAPE) is measure of accuracy in a fitted time series value in statistics, specifically trending. It usually expresses accuracy as a percentage, and is defined by the formula: where At is the actual value and Ft is the forecast value. The… … Wikipedia
Seat Allocation Error and Degree of Negation — The principle of proportional representation asserts that the share of the total seats of a party that is entitled to receive a seat is equal to its share of the total votes of all the parties that are entitled to receive a seat.The ideal number… … Wikipedia
Margin of error — This article is about the statistical precision of estimates from sample surveys. For safety margins in engineering, see Factor of safety. For tolerance in engineering, see Tolerance (engineering). Not to be confused with Margin for Error. The… … Wikipedia
Mean squared error — In statistics, the mean squared error (MSE) of an estimator is one of many ways to quantify the difference between values implied by a kernel density estimator and the true values of the quantity being estimated. MSE is a risk function,… … Wikipedia
Mean absolute scaled error — In statistics, the mean absolute scaled error (MASE) is a measure of the accuracy of forecasts . It was proposed in 2006 by Australian statistician Rob Hyndman, who described it as a generally applicable measurement of forecast accuracy without… … Wikipedia
Mean absolute error — In statistics, the mean absolute error (MAE) is a quantity used to measure how close forecasts or predictions are to the eventual outcomes. The mean absolute error is given by As the name suggests, the mean absolute error is an average of the… … Wikipedia
