Trimming of dyadic wavelet transform local extrema, using bootstrapping.
mbtrim(extrema, scale=FALSE, prct=0.95)
Structure containing
original signal.
trimmed extrema representation.
coarse resolution of signal.
number of decomposition scales.
size of signal.
dyadic wavelet transform extrema (output of ext
).
when set, the wavelet transform at each scale will be plotted with the same scale.
percentage critical value used for thresholding
The distribution of extrema of dyadic wavelet transform at each scale is generated by bootstrap method, and the 95% critical value is used for thresholding the extrema of the signal.
See discussions in the text of ``Practical Time-Frequency Analysis''.
