shd {causalDisco}

Structural hamming distance between adjacency matrices

Description

Computes the structural hamming distance between two adjacency matrices. This implementation is a modification of the shd function from the pcalg package, but here we avoid working on the heavy graphNEL objects for representing graphs that are used in the pcalg package.

Usage

shd(est_amat, true_amat)

Arguments

est_amat

Estimated adjacency matrix

true_amat

True adjacency matrix

Details

Note that the function is symmetric in the two inputted adjacency matrices.

Value

A numeric (a non-negative integer).
