Cluster Group View - Outlier Chart
Cluster Group View - Outlier Chart
To allow for easy detection of problematic groups of clusters in big data sets with disparate customer or trader
cluster volumes, the Outlier chart displays the percentage of high-risk clusters within an group's total clusters.
Outlier Chart display
The Outlier Chart display is organized into the following sections:
- Outlier Chart: Displays the Outlier view of the loaded 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 Outlier Chart
The Outlier Chart displays every cluster group's percentage of clusters with a score above a threshold defined by the
user. This allows for easy detection of problematic trading in big data sets with disparate customer or trader
The color of the dot indicates the severity of the score, with low scores represented as dark green and becoming
yellow and finally dark red as risk scores increase.
The position of a dot in the X-axis indicates the number of clusters contained in the dot.
The position of a dot in the Y-axis indicates the percentage of clusters that exceeded the score.

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).
