From: Algorithmic hospital catchment area estimation using label propagation
Classification agreement between activity based approach and label propagation algorithm. Each point is a unique combination of lower tier local authority and NHS trust and in panel A the proportion of the LTLA assigned to that trust is plotted for the activity based algorithm on the x-axis and the label propagation algorithm on the y-axis. In panel B the total number of cases assigned to each trust is plotted when the population size for the area is considered. The blue line represents perfect agreement
