A function to estimate the confidence intervals for irf and oirf.
errorBandsIRF(v, irf, alpha, M, resampling, ...)a var object as from fitVAR or simulateVAR
irf output from impulseResponse function
level of confidence (default alpha = 0.01)
number of bootstrapped series (default M = 100)
type of resampling: "bootstrap" or "jackknife"
some options for the estimation: verbose = TRUE or FALSE,
mode = "fast" or "slow", threshold = TRUE or FALSE.
a matrix containing the indices of the impulse response function that are 0.
