andrews_lrv {EncompassTest}

Long-run covariance estimation using Andrews quadratic spectral kernel.

Description

Given a vector of residuals, it generates the Heteroskedastic Long run variance.

Usage

andrews_lrv(e)

Arguments

e

a vector of residual series, for which we recommend to use the recursive residuals from larger model.

Value

a vector of Long run variance using Andrews quadratic spectral kernel HAC.
