The Kendalls Coefficient (KCC) correlation method was proposed previously to measure a regional homogeneity (ReHo) of the time series of a given voxel with those of its nearest neighbors in a voxel-wise analysis. Based on a hypothesis that ReHo could be modulated by epileptic neuronal activity, KCC analysis may be utilized to measure the similarity of time series of neuron activation on the resting-state fMRI data sets to distinguish the activity patterns between epileptic patients and healthy subjects.
