What does the Cluster tree show?
Overview
The Cluster tree groups codes, or documents, that pattern alike, using hierarchical clustering. You choose whether to cluster codes or documents, the linkage method, the number of clusters and how many items to include. Selecting a name shows its evidence. Use it to suggest candidate themes or groups of similar cases, and confirm them by reading the evidence. Find it under Analysis › Relations & Maps › Cluster Tree.
