Medical Cost Trajectories and Onsets of Cancer and NonCancer Diseases in US Elderly Population

Figure 1

Empirical estimates (dots) and model predictions (solid lines) of cost per month per capita. The diseases are ordered according to the cost of onset. Values in the right upper corners of all plots are 𝑋² per degree of freedom calculated as 𝑑𝑓⁻¹∑^20𝑖=20(𝐶_𝑖−𝐶(m))²/𝜎^2𝑖, where 𝐶_𝑖 and 𝜎_𝑖 are estimated mean and standard error of medical cost per month (for presentation purposes they were aggregated into two-month groups); 𝑑𝑓 denoted the degree of freedom calculated as the difference between the number of measured points (41) and the number of estimated parameters (4). Note that the scale of the vertical axes is not the same for different rows of plots.
