From brains to social networks and ecosystems, most often only a tiny fraction of the system can be observed. Such spatial subsampling can incur strong biases to measures as basic as the correlation strength. We derived an approach to overcome the subsampling-induced bias, which enables to infer the stability and distance to criticality – in principle from observing a single unit.

* This article became highlighted on the Complexity Channel: “This paper shows that a quite wide family of inputs can lead to the detection of signatures of criticality in a system which is otherwise noncritical, and proposes to extend the criticality analysis beyond looking at power laws, the most used signature of criticality. These results are generalizable to other complex systems.”
