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

In forecast: Forecasting Functions for Time Series and Linear Models

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.

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.

Value

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