    What is surrogation? It is easier to describe why it is used than what it is. In human studies, we usually ascribe nonlinear findings to the fact that the neuromuscular system is deterministic, that there was organization that drove the output. If this is true, shuffled data or random data should provide different results. Thus, we take the raw output data and shuffle it, so we know that the data are truly random, and rerun our nonlinear analysis. Do the nonlinear findings differ? We would hope so, but sometimes they do not. When they do not differ, that may indicate that the output was random and not from a deterministic source. Surrogation is underused in human studies and we would like to see if used more often to confirm our notions about deterministic origins.
