A. State fractional occupancy around the button press for different variations of the HMM–MAR: the HMM–Gaussian run on the Hilbert envelopes of the signal, an HMM–MAR where only the self-autoregression coefficients were allowed to vary, an HMM–crossMAR where only cross-channel coefficients were allowed to vary, and the HMM–MAR with uniformly-spaced lapses for Q = 1 and Q = 14. B. Examples of the state time courses for the HMM–Gaussian, HMM–MAR, HMM–AR and HMM–crossMAR. C. State life times and percentage of state occupancy for the HMM–Gaussian, HMM–MAR, HMM–AR and HMM–crossMAR.
