Figure 6From: Regional health care planning: a methodology to cluster facilities using community utilization patternsLocal minima and random starting locations with the K-means algorithm. 5,000 K-means model runs for K = 50 produced 5,000 unique cluster solutions (black line). A single model run of the K-means + Ward’s algorithm provided another unique cluster solution with a better fit (red point) than any of the 5,000 stand-alone K-means solutions.Back to article page
