Invoke contribution analysis in a project.

1. In a Line visualization, based on a freeform table with daily granularity, select an anomaly data point. From the popup, select Analyze.

2. In a freeform table with daily granularity, from the context menu on any row, select Run contribution analysis. You can even run the analysis on rows that do not display any anomaly.

3. In a freeform table with daily granularity, on a row that indicates an anomaly:

   1. Select the indicator â—¥.
   2. From the Anomaly detected dialog, select Open Contribution Analysis.

(Optional) You can narrow the scope of (and thus speed up) the analysis by excluding dimensions.

Select Run contribution analysis.

Wait while the contribution analysis is processed. The processing can take a considerable amount of time, depending on the size of your report suite and the number of dimensions. Contribution analysis performs analysis on the top 50,000 items per dimension. You are also notified about the number of contribution analysis tokens remaining.

Analysis Workspace loads a new Contribution analysis panel directly within this project.

• A summary number visualization.

• A monthly trended line visualization.

• A Top Items freeform table that displays which top items contribute to this anomaly, sorted by Contribution score. The additional columns show the metric in question, and a Unique Visitors metric to provide context.

• The Generated Segments (Top Item Clusters) freeform table identifies associations of top items based on the Contribution Score, anomaly occurrences, and overall percentage contributing to the anomalous metric. This association is then captured as an audience segment (Contribution Segment 1, Contribution Segment 2, etc.). Select to display the segment’s definition, including which top items the segments is made up of:

Since contribution analysis is now part of Analysis Workspace, you can take advantage of a number of its features from a freeform table context menu to make your analysis even more meaningful, such as:

• Break down each dimension item by another dimension
• Trending one or more rows
• Add a new visualizations
• Create alerts
• Create or compare segments.
