define_density_mass_grid
(density, num_levels=None)¶ Create a grid of density levels with a uniform number of points between each level.
Parameters: density : numpy array[float] or list[float]
Values of a density estimate.
num_levels : int, optional
Number of density levels in the grid. This is essentially the vertical resolution of a level set tree built from the ‘density’ input.
Returns: levels : numpy array
Grid of density levels that will define the iterations in level set tree construction.

Notes
- The level set tree is constructed by filtering a similarity graph according to this grid. This function simply defines the density levels, but it does not do the actual tree construction.
