After training and appropriate validation on independent tests sets, this SVR model is able to estimate the resolution of solved X-ray structures with a correlation coefficient of 0.92, mean absolute error of 0.28 Angstroms.

Yezioro, Dong and Leite developed an artificial intelligence approach towards assessing building performance simulation results and found that more detailed simulation tools have the best simulation performance in terms of heating and cooling electricity consumption within 3 % of mean absolute error.

As the name suggests, the mean absolute error is an average of the absolute errors | e _ i | = | f _ i-y _ i |, where f _ i is the prediction and y _ i the true value.

A 2001 paper by Roy Batchelor of City University Business School, London compared the Consensus Forecasts with forecasts made by the International Monetary Fund ( IMF ) and the OECD . The study found : " With few exceptions, the private sector forecasts are less biased and more accurate in terms of mean absolute error and root mean square error.

The main difference with the method for non-seasonal time series, is that the denominator is the mean absolute error of the one-step " seasonal naive forecast method " on the training set, which uses the actual value from the prior season as the forecast : " F " " t " = " Y " " t " " m, where m is the seasonal period.
