This code package implements the density integration methodology for BOS outlined in:

sample_script.py is a sample python script that loads the sample dataset in 'sample-data.mat' and calls the density integration + uncertainty quantification function to perform the calculations. It saves the result to 'sample-result.mat' and a figure to 'sample-result.png'
