mbtrim: Trim Dyadic Wavelet Transform Extrema

Description Usage Arguments Details Value References See Also

Description

Trimming of dyadic wavelet transform local extrema, using bootstrapping.

Usage

1
mbtrim(extrema, scale=FALSE, prct=0.95)

Arguments

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

percentage critical value used for thresholding

Details

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.

Value

Structure containing

original

original signal.

extrema

trimmed extrema representation.

Sf

coarse resolution of signal.

maxresoln

number of decomposition scales.

np

size of signal.
