Figure 40. Length of stay by hospital for cardiovascular surgery
Figure 41. Total charges by hospital for cardiovascular surgery
of a short length of stay. The ordering of the procedures is completely different for the two hospitals.
We do a final examination in Figure 42 for hospital #1.
In this figure, it is clear that procedure 3612 has the highest probability of a long length of stay while
3611 has a high probability of a short length of stay. In other words, we have three different hospitals and
they have three very different graphs, indicating that there is almost no relationship between procedure
and length of stay when comparing the different hospitals.
We use predictive modeling to determine whether length of stay and total charges can be predicted.
Dmine regression gives the best estimate (Figure 45).
