About the Segment Profile node
One of the best time-saving nodes is the Segment Profile node. This node determines which variables are statistically important for differentiating each individual segment and produces easily understood plots. You can use it with ANY data with a variable set to the "segment" role, as well as after segmentation is carried out in EM (Cluster, Decision Tree, SOM/Kohonen nodes).
Any variable with the role "input" is used as a possible profile variable so you can profile using variables that were not used in the segmentation algorithm.
Profile variables are displayed horizontally in descending order of importance for each segment. Then it’s just a matter of “spot the difference” to understand how these variables differ in a segment compared to overall.
How to visualize variable distribution using the Segment Profile Node
By default the distribution charts (segment vs overall) are displayed for the most significant variables in each segment, which can be different for each.
If you want to see the same variables aligned for all segments or want to see the distribution of a completely new variable, simply click Edit Variables on Segment Profile Node and then choose Use =No and Report=Yes for the variables that you would like to visualize in the Results report.
Check out these example screenshots.
