Null models and their utility in measuring small-worldness in dynamic graphs. (a) Schematic of the edge rewiring process for the randomized edges (RE) model. (b) Schematic of the randomly permuted times (RP) model where contact times are permuted uniformly at random. (c) Temporal correlation coefficients for one session of a participant in the study (black dashed line), and the 100 runs of the RE and RP model created from this dynamic network. (d) Small-worldness calculations using either the RE (purple) or RP (blue) null model. Toolbox functions used include randomized-Edges, randPermutedTimes, temporalCorrelation, and temporalSmallWorldness.
