Fig. 5From: Expenditure variations analysis using residuals for identifying high health care utilizers in a state Medicaid programScatter plot of rank percentiles of residuals: 2013 and 2014. On the left is the scatter plot for overall population. We can visually recognize the temporal correlation as the scatter points are denser on the diagonal from lower left to upper right. On the right is the scatter plot for high utilizers. The temporal correlation for the high utilizers is even stronger than for other patients. Most patients with high residuals in 2013 (top 5%) remain in the high residuals population in 2014 (top of the scatter plot)Back to article page
