data_value_rank ( self,  value )

Find the fraction of voxels that hove lower data value. Result is an approximation using binned data.

cumulative_counts ( self )

mass_rank_data_value ( self,  fraction )

Find the data value where a specified fraction of total mass above that data value is a given fraction of total mass of non-negative voxels. Result is an approximation using binned data.

bin_counts ( self,  bins )

Compute histogram from binned data using a different number of bins.

rank_data_value ( self,  fraction )

Find the data value where a specified fraction of voxels have lower value. Result is an approximation using binned data.

cumulative_mass ( self )

bin_range ( self,  bins )

Return center positions of first and last bin, and bin size.
