This approximation has a maximum absolute error of less than 0.9 % for 1 to 19 outs and a maximum relative error of 3.5 % for more than 3 outs.
32.
If no significant bias is present in the forecast, then the smoothed error " E t " should be small compared to the smoothed absolute error " M t ".
33.
The check is based on the bracket size relative to its central value, because that relative error in x is approximately proportional to the squared absolute error in f ( x ) in typical cases.
34.
He has neglected to distinguish readings of " prima manu " from the corrections made by later hand, both in the text and margin, but Scrivener very seldom detected him in absolute error.
35.
For example, when an absolute error in a temperature measurement given in Celsius is 1?and the true value is 2 �C, the relative error is 0.5 and the percent error is 50 %.
36.
The mean absolute error is a common measure of forecast error in time series analysis, where the terms " mean absolute deviation " is sometimes used in confusion with the more standard definition of mean absolute deviation.
37.
It occurs when an operation on two numbers increases relative error substantially more than it increases absolute error, for example in subtracting two nearly equal numbers ( known as "'catastrophic cancellation "').
38.
Likewise, the "'sum of absolute errors "'( SAE ) refers to the sum of the absolute values of the residuals, which is minimized in the least absolute deviations approach to regression.
39.
Reliability-seeking organizations are not distinguished by their absolute errors or accident rate, but rather by their effective management of innately risky technologies through organizational control of both hazard and probability ( p . 14 ).
40.
Where a prediction model is to be fitted using a selected performance measure, in the sense that the least squares approach is related to the mean squared error, the equivalent for mean absolute error is least absolute deviations.
