calculate_varex(*, component_maps: ndarray) → ndarray

Calculate relative coefficient energy from parameter estimate maps.

This measure indicates the relative coefficient magnitude across voxels for each component.

Parameters:

component_maps ((S x C) array_like) – Component-wise parameter estimates from the regression of the optimally combined data against component time series.

Returns:

varex ((C) array_like) – Average (across voxels) relative coefficient energy for each component, on a scale from 0 to 100.
