1. A method for determining dimensionality of a network, the dimensionality corresponding to a number of degrees of freedom in the network, the method comprising the steps of: using a computer system, sampling data from one or more nodes of the network; using the computer system, mapping the data into one or more matrices; using the computer system, applying individual differences multidimensional scaling to the one or more matrices to produce a stress/energy; and using the computer system, processing the stress/energy to determine the dimensionality of the network.
