Subsampling test of Whang and Kim (2003)

Description

The function returns the p-values of the subsampling test.

Usage

Subsample.test(y, kvec)

Arguments

y	a vector of time series, typically financial return
kvec	a vector of holding periods

Details

The block lengths are chosen internally using the rule proposed in Whang and Kim (2003)

Value

Holding.Period	holding periods used
Block.Length	block lengths chosen
pval	p-values of the test for each block length used

Examples

data(exrates)
y <- exrates$ca                  
nob <- length(y)
r <- log(y[2:nob])-log(y[1:(nob-1)])   
kvec <- c(2,5,10)
Subsample.test(r,kvec)
