Box-Cox and Loess-based decomposition bootstrap.
Generates bootstrapped versions of a time series using the Box-Cox and Loess-based decomposition bootstrap.
bld.mbb.bootstrap(x, num, block_size = NULL)
x |
Original time series. |
num |
Number of bootstrapped versions to generate. |
block_size |
Block size for the moving block bootstrap. |
The procedure is described in Bergmeir et al. Box-Cox decomposition is applied, together with STL or Loess (for non-seasonal time series), and the remainder is bootstrapped using a moving block bootstrap.
A list with bootstrapped versions of the series. The first series in the list is the original series.
