MDR, Simulated mean discharge rates; : the MDR estimated by the proposed algorithm; CoV, Simulated coefficient of variability for the firing rate; , CoV estimated by the proposed algorithm; SIR: average signal-to-interference ratio; cDI: cumulative Decomposability Index. MDR and CoV biases were calculated as the absolute mean value of the pair-wise difference between estimated minus gold standard MDR and CoV, respectively.
