Baruník and Křehlík (2018) frequency connectedness approach

Description

This function calculates the Baruník and Křehlík (2018) frequency connectedness measures.

Usage

FrequencyConnectedness(
  Phi,
  Sigma,
  nfore = 100,
  partition = c(pi, pi/2, 0),
  generalized = TRUE,
  orth = FALSE,
  scenario = "ABS",
  corrected = FALSE
)

Arguments

Phi	VAR coefficient matrix
Sigma	Residual variance-covariance matrix
nfore	H-step ahead forecast horizon
partition	Frequency spectrum
generalized	Orthorgonalized/generalized FEVD
orth	Orthorgonalized shocks
scenario	ABS or WTH
corrected	Boolean value whether corrected or standard TCI should be computed

Value

Get connectedness measures

Examples

data("dy2012")
partition = c(pi+0.00001, pi/4, 0)
fit = VAR(dy2012, configuration=list(nlag=4))
dca = FrequencyConnectedness(Phi=fit$B, Sigma=fit$Q, nfore=100, partition=partition)
