pygwb.spectral.coarse_grain_exact(data, coarsening_factor)[source]

Coarse grain an array using any coarsening factor.

Each bin will contain the integral of the input array covering coarsening_factor bins.

This is done by evaluating the difference between the cumulative integral of the data at the beginning and end of each bin.

The i’th bin covers [coarsening_factor * (ii - 0.5), coarsening_factor * (ii + 0.5)] indexed for 1 <= ii < len(data) / coarsening_factor.

Parameters:

  • data (array-like) – The data to coarse grain.

  • coarsening_factor (float) – The factor by which to coarsen the data.

Returns:
output: array-like

The coarse-grained data.
