Outputs by Cluster Identifier
Top Ranking Centroids Indices
This option allows you to add to the output file the number of the clusters whose centroids are the closest to
the current observation. The closest cluster is the one the observation belongs to, its number is displayed in
the column kc_<Target variable>. The next closest cluster is displayed in the column kc_<Target Variable>_2,
and so on until the furthest cluster. you can choose to add all the clusters or only the closest.
 To Add All the Clusters
Check the All option.
 To Add Only the Closest Clusters
1
Check the Top option.
2
In the text field enter the number of clusters you want to add (for example, the two, three or four closest).
Top Ranking Centroids Names
This option allows you to add to the output file the names of the clusters whose centroids are the closest to the
current observation. The closest cluster is the one the observation belongs to, its name is displayed in the
column kc_name_<Target variable>. The next closest cluster is displayed in the column kc_name_<Target
Variable>_2, and so on until the furthest cluster. You can choose to add all the clusters or only the closest.
 To Add All the Clusters
Check the All option.
 To Add Only the Closest Clusters
1
Check the Top option.
2
In the text field enter the number of clusters you want to add (for example, the two, three or four closest).
Note
The name of a cluster is by default its number, you can modify this in the column User Name of the
panel Clusters Profiles accessible through the main menu.
Top Ranking Distan ces
This option allows you to add to the output file the distances of each observation from the clusters centroids.
The distance from the closest centroid is displayed int the column kc_best_dist_<TargetVariable>, the
distance from the second closest centroid is displayed in the column kc_best_dist_<TargetVariable>_2, and so
on until the furthest centroid. You can add the distances from all centroids or only the shortest.
 To Add All the Distances
Check the All option.
 To Add Only the Shortest Distances
1
Check the Top option.
2
In the text field enter the number of distances you want to add (for example, the two, three or four
shortest).
Note
When the SQL mode is activated, the notion of nearest cluster does not exist. If a case belongs to a
cluster, distance is set to 0. If a case does not belong to a cluster, distance is set to 1.
