bld.mbb.bootstrap: Box-Cox and Loess-based decomposition bootstrap.

Description

Generates bootstrapped versions of a time series using the Box-Cox and Loess-based decomposition bootstrap.

Usage

bld.mbb.bootstrap(x, num, block_size = NULL)

Arguments

x

Original time series.

num

Number of bootstrapped versions to generate.

block_size

Block size for the moving block bootstrap.

Value

A list with bootstrapped versions of the series. The first series in the list is the original series.

Details

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.
