- calculate_z_maps(weights, z_max=8)[source]
Calculate component-wise z-statistic maps.
This is done by z-scoring standardized parameter estimate maps and cropping extreme values.
- Parameters:
weights ((M x C) array_like) – Standardized parameter estimate maps for components.
z_max (float, optional) – Maximum z-statistic, used to crop extreme values. Values in the z-statistic maps greater than this value are set to it.
- Returns:
z_maps ((M x C) array_like) – Z-statistic maps for components, reflecting voxel-wise component loadings.
