Compare two weighted networks

Compare two weighted networks

Usage

compare_networks(x, y, threshold = 0)

Arguments

x, y

Supported network representations.

threshold

Absolute weight threshold for edge presence: a dyad counts as an edge when abs(weight) > threshold.

Value

A one-row base data.frame with columns pearson, cosine, mae, rmse, jaccard, edges_x, and edges_y. pearson and cosine are NA when either network's aligned weights have no variance or are all zero.

Details

The two networks are aligned on the union of the dyads that carry an edge in either network; dyads absent from both are excluded, so every metric is conditional on that union rather than on all possible dyads.

Examples

a <- simulate_network(nodes = 30, model = "bernoulli", probability = 0.1, seed = 1)
b <- simulate_network(nodes = 30, model = "bernoulli", probability = 0.1, seed = 2)
