When r = 1, the network is said to have perfect assortative mixing patterns, when r = 0 the network is non-assortative, while at r = −1 the network is completely disassortative.
The degree of assortative mixing in a network is quantified by the parameter r. A value of 1 signifies perfect clustering, while a value of 0 indicates no correlation between nodes. Conversely, an r value of −1 implies that the network consists entirely of disassortative connections.
