Web1. A standard Gaussian random vector is also Gaussian (with A =I and =0). 2. For any c, a vector in n, the random variable c tx ∼ tct c AA c (A.11) this follows directly from (A.6). … WebBoth iid and non-iid noise induce transitions from non-coherent non-rhythmic states to coherent oscillating states. To describe the observed phase transitions, we derive analytically a deterministic order parameter equation [ 17] where additive noise transforms the dynamics through a novel noise-dependent non-linear response function.
