Create an impulse-response restriction specification

Usage

irf_restriction(variable, shock, horizon, sign = NULL, zero = FALSE)

Arguments

variable: Response variable.
shock: Shock.
horizon: Horizon.
sign: Optional sign restriction, typically 1 or -1.
zero: If TRUE, treat the restriction as a zero restriction.

Value

A list of class bsvar_post_irf_restriction (inheriting from bsvar_post_restriction) with elements variable, shock, horizon, sign, and zero.

Examples

r <- irf_restriction("gdp", "gdp", 0, sign = 1)
print(r)
#> $variable
#> [1] "gdp"
#> 
#> $shock
#> [1] "gdp"
#> 
#> $horizon
#> [1] 0
#> 
#> $sign
#> [1] 1
#> 
#> $zero
#> [1] FALSE
#> 
#> attr(,"class")
#> [1] "bsvar_post_irf_restriction" "bsvar_post_restriction"
