var_irf {sovereign} | R Documentation |
Estimate impulse response functions
Description
Estimate impulse response functions
Usage
var_irf(
var,
horizon = 10,
CI = c(0.1, 0.9),
bootstrap.type = "auto",
bootstrap.num = 100,
bootstrap.parallel = FALSE,
bootstrap.cores = -1
)
Arguments
var |
VAR output |
horizon |
int: number of periods |
CI |
numeric vector: c(lower ci bound, upper ci bound) |
bootstrap.type |
string: bootstrapping technique to use ('auto', 'standard', or 'wild'); if auto then wild is used for IV or IV-short, else standard is used |
bootstrap.num |
int: number of bootstraps |
bootstrap.parallel |
boolean: create IRF draws in parallel |
bootstrap.cores |
int: number of cores to use in parallel processing; -1 detects and uses half the available cores |
Value
data.frame with columns target
, shock
, horizon
, response.lower
, response
, response.upper
