## 6 Application to Geriatric Assessment Survey
### Mood Questions  
Patients were asked to what extent they agreed with statements concerning how they have been feeling, on the average, in the past week. A total of 750 historical surveys were available to analyze these questions. The responses were coded as \"0\" if the patient did not agree very much with the statement and \"1\" if the patient generally agreed. The statements presented to the patient are shown in Table 5.  
\begin{table}
\begin{tabular}{c c c} \hline \hline
**Question** & **Previous Answers** & **Presumed Answer** \\ \hline
1 & NA & 0 \\
3 & 00 & 0 \\
6 & 00000 & 0 \\
7 & 00000 & 0 \\ \hline \hline \end{tabular}

Table 3: Daily activities and their mined branching rules (Budget is 1%); (0 = needed no help, 1 = needed some or a lot of help).  
The inputted _budget_ for the number of changed answers in the historical surveys was 1% of the 10,500 total number of answers provided, or 105 answers. The inputted _min.bnetfit_ was 50. The results in Table 6 provide the information needed to implement the mined branching rules into the survey. The overall cost of eliminating the 16 CQs is 101 and the total number of saved questions is 3474, yielding a 33.1% reduction in the total number of questions asked. Branching rules corresponding to the eliminated CQs identified in Table 6 are shown in Table 5.
