Cluster List View
Cluster List View
The Cluster List view shows individual clusters created from the selected dates. Each row of this sortable list is
highlighted with a color to indicate the severity of that cluster's risk score.
Cluster List display
The Cluster List display is organized into the following sections:
- Cluster List: Displays the Cluster List view of the selected dates' data as well as
filtering and navigation tools.
- Data Selection Panel: Manages the dates available to TT Score and specifies
the criteria to use when populating the list.
Interpreting the Cluster List
The Cluster List is used to conduct a cluster list review. Once a problematic cluster group is identified, you can
inspect the individual clusters contained in that group using the Cluster Scorecard. This Score column is color
coded using a graduated scale tied to the risk score, transitioning from red through yellow to green and pale green
as scores decrease.
While conducting a cluster list review, it can be helpful to:
- Filter out lower scoring clusters using the Score filter to make larger datasets more
- Sort the list by Start Time to see if higher scoring clusters bunch up at particular times of

Visible models in the Data Selection Panel
The TT Score Dashboard settings in the Preferences | Models Defaults - Visibility & Range section determine which models are visible in the panel and what range of cluster scores are included in the cluster data views.
When you click the Surveillance tab to show the Data Selection Panel, the MODELS section is filtered based on your visibility preferences. By default, all checkboxes are checked for the visible models and the SCORE RANGE is 1-100.
As you check each visible model, the SCORE RANGE displays the range preference set for the selected model (e.g., 60-100).
