nse.hiruk: Hirukawa NSE estimators.

In braverock/nse: Numerical Standard Errors Computation in R

Description

Calculate the variance of the mean with the kernel based variance estimator by Andrews (1991) using Hirukawa (2010) automatic bandwidth estimator.

Usage

nse.hiruk(x, type = c("bartlett", "parzen"), lag.prewhite = 0)

Arguments

x	A numeric vector.
type	The type of kernel used c("Bartlett","Parzen").
lag.prewhite	Prewhite the serie before analysis (integer or NULL, i.e. automatic selection)

Details

This is a wrapper around lrvar from the sandwich package and use Hirukawa (2010) automatic bandwidth estimator.

Value

The variance estimator.

Examples

n    = 1000
ar   = 0.9
mean = 1
sd   = 1

set.seed(1234) 
x = as.vector(arima.sim(n = n, list(ar = ar), sd = sd) + mean)
 
nse.hiruk(x = x, type = "bartlett", lag.prewhite = 0)
nse.hiruk(x = x, type = "bartlett", lag.prewhite = 1)
nse.hiruk(x = x, type = "bartlett", lag.prewhite = NULL)

nse.hiruk(x = x, type = "parzen", lag.prewhite = 0)
nse.hiruk(x = x, type = "parzen", lag.prewhite = 1)
nse.hiruk(x = x, type = "parzen", lag.prewhite = NULL)
