calculate_dependence_metrics(f_t2_maps, f_s0_maps, z_maps)[source]

Calculate Kappa and Rho metrics from F-statistic maps.

Just a weighted average over voxels.

Parameters:

  • f_t2_maps, f_s0_maps ((S x C) array_like) – Pseudo-F-statistic maps for TE-dependence and -independence models, respectively.

  • z_maps ((S x C) array_like) – Z-statistic maps for components, reflecting voxel-wise component loadings.

Returns:

kappas, rhos ((C) array_like) – Averaged pseudo-F-statistics for TE-dependence and -independence models, respectively.
