Accelerometer signal features.

Feature	Equation	Description
Mean		The mean of the signal for each subject
Standard deviation		The standard deviation of the signal is calculated for each value
Correlation		The correlation coefficient between the two accelerometer signals
Kurtosis		Kurtosis shows the peakedness of a signal
Crest factor		It shows the signal impulsiveness with the maximum accelerometer value
