Least absolute deviation and least square method are generally used to measure the distance between two traces, and their expressions are as follows:
The features extracted are Entropy, Energy, Standard Deviation and Mean absolute deviation.
Detecting outliers: Do not use standard deviation around the mean, use absolute deviation around the median.

The right of the table shows rate of rejection when there is no effect (the rate of false rejection), a small effect, and a medium effect, as well as the mean absolute deviation between the estimated point estimate and the true program effect.

The Autoregressive Integrated Moving Average models are used to produce forecasts of long-term total indirect tax and federal revenue collections, which seem to give minimum forecast errors based on a nonparametric Mean Absolute Deviation (MAD) test.
