A function to estimate the confidence intervals for irf and oirf.
error_bands_irf(v, irf, alpha, m, resampling, ...)a matrix containing the indices of the impulse response function that are 0.
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.
