Arguments

x

A time series defining the scenario-probability distribution.

p

An object of the ffp class.

n

An integer scalar with the number of scenarios to be generated.

Details

The argument x is supposed to have the same size of p.

Value

A tibble with the number of rows equal to n.

Examples

set.seed(123)
ret <- diff(log(EuStockMarkets))
ew  <- rep(1 / nrow(ret), nrow(ret))

bootstrap_scenarios(x = ret, p = as_ffp(ew), n = 10)
