get.thres: Universal thresholds calculation

In wbsts: Multiple Change-Point Detection for Nonstationary Time Series

Description

The function returns universal thresholds and the method is described in Korkas and Fryzlewicz (2017) and Cho and Fryzlewicz (2012). See also the supplementary material for the former work. The function works for any sample size.

Usage

get.thres(n, q=.95, r=100, scales=NULL)

Arguments

n	The length of the time series.
q	The quantile of the r simulations.
r	Number of simulations.
scales	The wavelet periodogram scales to be used. If NULL (DEFAULT) then this is selected as described in the main text.
