fd_RR | R Documentation |
Relative Rougness is a ratio of local variance (autocovariance at lag-1) to global variance (autocovariance at lag-0) that can be used to classify different 'noises'.
fd_RR(y)
y |
A numeric vector. |
RR = 2 * \left[1 - \frac{\gamma(y)}{Var(y)}\right]
The Relative Roughness of y, the values of local and global variance are returned as attributes
