The node you select in the Decision Tree pane of the Performance Models window determines what data set will be used in analysis. The data set is that which fits the criteria of the selected node and its ancestors. (To see the criteria for a node, hover over the node and the system will display the decision criteria.)
To select a data set for analysis, use the following steps:
- Display the Performance Models window.
- In the left pane, click the node that corresponds to the data set you wish to use in analysis.
To graph the data set, right-click the node and select Analyze Model. The system displays the Analyze Model window that shows a condition versus age plot of all data points in the set. To determine the number of data points in the data set, click the Models tab. The NUM SAMPLE column in the right pane identifies the number of points in the data set.
