- B . Decision trees cannot handle missing values.
- C . Decision trees can be used for classification and estimation.
- D . Decision trees cannot handle continuous dependent variables.
How can you interpret a Parallel Coordinates plot in cluster analysis?
- A . It shows the distribution of data within a cluster.
- B . It visualizes the relationship between clusters.
- C . It displays the hierarchical structure of clusters.
- D . It provides a summary of cluster statistics.
When reviewing Measure Details in SAS Visual Analytics, what information can you find related to measures?
- A . Measure name and label
- B . Measure format and informat

You have a regression model effect that represents the total amount of sales. In addition to that, you would like to create a model effect that represents the average amount of sales.
Which option should you use?
- A . Create an aggregated measure using the Avg aggregation on total amount of sales.
- B . Create a calculated item that divides total amount of sales by the total amount of items sold.
- C . Create a calculated item by duplicating the original model effect and changing its default aggregation to Average.
- D . Create an aggregated measure using the Sum aggregation of total amount of sales divided by the Sum aggregation of total amount of items sold.
What roles can be assigned to variables in logistic regression?
- A . Input
- B . Target
- C . Nominal
- D . Interval
How can you interpret a Tree Map in the context of a decision tree?
- A . It visualizes the distribution of data points in leaf nodes.
- B . It displays the hierarchical structure of the decision tree.
- C . It shows the decision boundaries between classes.
- D . It summarizes the performance metrics of the decision tree.
Why are decision trees a useful technique for segmentation?
- A . Trees split the response into homogeneous groups, while maximizing the difference in the response of the groups.
- B . Trees split the response into heterogeneous groups, while minimizing the difference in the response of the groups.
- C . Trees split data into smaller cells which are decreasingly “pure”.
- D . Trees treat each split cell dependently based on earlier split decisions.
