threshold {fnets}

Threshold the entries of the input matrix at a data-driven level

Description

Threshold the entries of the input matrix at a data-driven level. This can be used to perform edge selection for VAR parameter, inverse innovation covariance, and long-run partial correlation networks.

Usage

threshold(mat, path.length = 500)

Arguments

mat

input parameter matrix

path.length

number of candidate thresholds

Details

See Owens, Cho & Barigozzi (2024+) for more information on the threshold selection process

Value

an S3 object of class threshold, which contains the following fields:

threshold

data-driven threshold

thr.mat

thresholded input matrix
