View source: R/retrieveBootstrapSample.R

Use the wavelet coefficients from the selected WiSE bootstrap model to construct smooth bootstrap series in the original time/space domain. This function may be of little use and creates large array objects within R. The wavelet coefficients are a preferable representation of the data, as they are sparse and contain the signal information.

The `wavethresh`

package is used to perform the inverse wavelet decomposition of each bootstrap sample of wavelet coefficients.

The bootstrap series will be smoothed to the selected threshold level, *J0=j* (see `WiSEBoot`

).

` BootSample ` |
an array. The rows contain each bootstrap sample – dimension is the |
