Distance Correlation for ROI Time Series

Description

Computes the distance correlation (Yoo et al., 2019) for ROI time series data. This function is mainly a subroutine for the dCor.parallel function

Usage

dCor(neurallist, centering = c("U", "double"))

Arguments

neurallist

List. A time series list from convertConnBrainMat function

centering

Character. Options for centering the Euclidean distances.

• "U" Uses number of time points minus 2 in the computation of the mean

• "double" Uses the mean

Value

Returns a m x m matrix corresponding to distance correlations between ROIs
