mntrim {Rwave} | R Documentation |
Trimming of dyadic wavelet transform local extrema, assuming normal distribution.
mntrim(extrema, scale=FALSE, prct=0.95)
extrema |
dyadic wavelet transform extrema (output of ext ).
|
scale |
when set, the wavelet transform at each scale will be plotted with the same scale. |
prct |
The distribution of extrema of dyadic wavelet transform at each scale is generated by simulation, assuming a normal distribution, and the 95% critical value is used for thresholding the extrema of the signal.
