R: Trim Dyadic Wavelet Transform Extrema

mbtrim {Rwave} | R Documentation

## Trim Dyadic Wavelet Transform Extrema

### Description

Trimming of dyadic wavelet transform local extrema, using bootstrapping.

### Usage

    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.

See discussions in the text of “Practical Time-Frequency Analysis”.
