long_run_covariance_estimation: Estimating long-run covariance function for a functional time series

Description

Bandwidth estimation in the long-run covariance function for a functional time series, using different types of kernel function

Usage

Arguments

dat

A matrix of p by n, where p denotes the number of grid points and n denotes sample size

C0

A tuning parameter used in the adaptive bandwidth selection algorithm of Rice

H

A tuning parameter used in the adaptive bandwidth selection algorithm of Rice

Value

An estimated covariance function of size (p by p)
