idio.seg: Multiple change-point detection for the idiosyncratic components

Description

First generating the panel of statistics via wavelet-based filtering of the estimated idiosyncratic components, it applies the Double CUSUM Binary Segmentation in combination with the bootstrap generated thresholds to estimate the multiple change-points in the idiosyncratic components.

Usage

idio.seg(gfm, q, scales = NULL, diag = TRUE, sig.lev = 0.05, rule = NULL, B = 200, p = NULL, dw = NULL, mby = NULL, tby = NULL, do.parallel = TRUE)

Arguments

gfm
a get.factor.model object with estimates of the factor structure
q
the number of factors
scales
see scales in factor.seg.alg
diag
see idio.diag in factor.seg.alg
sig.lev
see sig.lev in factor.seg.alg
rule
the height of a binary tree for change-point analysis, see the Appendix of Barigozzi, Cho & Fryzlewicz (2016)
B
the size of bootstrap samples
p
see p in factor.seg.alg
dw
see dw in factor.seg.alg
mby
see dmby in func_dc_by
tby
see dtby in func_dc_by
do.parallel
see do.parallel in factor.seg.alg
