Before revision:  The results show that despite apparently uncoupled joint probabilities, the couplings possess some aspects which diverge from random Gaussian noise. Thereby, with the aid of the network's topological and statistical measurements , we distinguished basic structures of coupling of cross-market networks.
After revision:  The results show that despite apparently uncoupled joint probabilities, the couplings possess some aspects which diverge from the same features of the network mapped from white noise, and from the network mapped from two surrogate time-series. These deviations prove that there exist joint information and cross-correlation therein. By applying the network's topological and statistical measurements , we distinguished basic structures of coupling of cross-market networks.
