Connectedness Approach

Description

This function provides a modular framework combining various models and connectedness frameworks.

Usage

ConnectednessApproach(
  x,
  nlag = 1,
  nfore = 10,
  window.size = NULL,
  corrected = FALSE,
  model = c("VAR", "QVAR", "LAD", "LASSO", "Ridge", "Elastic", "TVP-VAR", "DCC-GARCH"),
  connectedness = c("Time", "Frequency", "Joint", "Extended Joint", "R2"),
  VAR_config = list(QVAR = list(tau = 0.5, method = "fn"), ElasticNet = list(nfolds = 10,
    alpha = NULL, loss = "mae", n_alpha = 10), TVPVAR = list(kappa1 = 0.99, kappa2 =
    0.99, prior = "BayesPrior", gamma = 0.01)),
  DCC_config = list(standardize = FALSE),
  Connectedness_config = list(TimeConnectedness = list(generalized = TRUE),
    FrequencyConnectedness = list(partition = c(pi, pi/2, 0), generalized = TRUE,
    scenario = "ABS"), R2Connectedness = list(method = "pearson", decomposition = TRUE,
    relative = FALSE))
)
