Question

1. Generate lots of trees. 2. See how many times you get the same groupings across all the trees. 3. The bootstrap support value is labeled at the node. What is the purpose of generating multiple trees and analyzing their groupings?

1) To determine the most common grouping across all the trees
2) To identify the bootstrap support value for each node
3) To compare the groupings obtained from different trees
4) To visualize the hierarchical structure of the data

Answer 1

The purpose of generating multiple trees and analyzing their groupings is to identify the most common grouping across all the trees and visualize the hierarchical structure of the data

How to explain

Generating multiple trees helps capture the variability and uncertainty in the data, while analyzing their groupings allows us to determine which groupings are most robust and reliable.

Bootstrap support values, labeled at each node, indicate the percentage of trees that support a specific grouping, providing an estimate of its confidence
