Figure 14. Probability density of total charges with and without immune disorder
Figure 15 shows the probability density for length of stay; Figure 16 shows it for total charges. Note
that the probability curves for septicemia alone, or septicemia and pneumonia are nearly identical. This
indicates that septicemia is the more crucial condition, and pneumonia does not add to the required time
or cost of treatment.
We next look at immune disorder and pneumonia (Figures 17 and 18). In this case, it is clear that
there is a difference. The peak for either the immune disorder or pneumonia is approximately 3.15 days
(versus 2 days for neither condition). However, the peak is at 4.9 days for patients with both conditions,
