Segments are subsets of users, who are assigned to segments based on rules. Since any person can belong to multiple segments, reporting on sales by segment can result in the appearance of inflated revenue; segment clusters provide a more precise view of how people group themselves.
Three query subjects are related to segments. The Segment query subject lists segments. The Segment Cluster query subject identifies all possible combinations of segments. The Segment Cluster Members query subject identifies segments with the clusters of which they are members.
Size refers to the number of segments in the cluster.
The Segment regular dimension includes two hierarchies, one of which includes the segment cluster data, the other only the Segment and Segment (All).
