How to decide which segmentation is better ?
As a side effect of the supervision, InfiniteInsight® Modeler - Segmentation/Clustering provides you with a KI
and KR. It can be used to compare the two segmentations (especially because the number of segments is the
same). If KI does not change significantly, then the one with SQL may be preferred because it is easier to
understand. If there is a fall of KI, you may want to stick with the basic segmentation.
KI may not be the thing you want to optimize for segmentation. The target profile of each segment is available
in the GUI. Out of the four clusters, maybe one or two are of real interest. In that case you have to focus on
these interesting segments and see how they evolve with SQL generation.
Statistical Reports
The Statistical Reports provide you with a set of tables that allows you a more detailed debriefing of your
model. These reports are grouped in different levels of debriefing:

the Descriptive Statistics, which provides the statistics on the variables, their categories and the data
sets, as well as the variables cross-statistics with the target .
Note
If your data set contains date or datetime variables, automatically generated variables will appear
in the statistical reports. For more information, refer to section Date and Datetime Variables:
Automatically Generated Variables (on page 30).



the Model Performance, in which you will find the model performance indicators, the variables
contributions and the score detailed statistics.
the Control for Deviations, which allows you to check the deviations for each variable and each variable
category between the validation and test data sets.
the Expert Debriefing, in which you will find more specialized performance indicators, as well as the
variables encoding, the excluded variables during model generation and the reason for exclusion and so
on.
Statistical Reports Options
A tool bar is provided allowing you to modify how the current report is displayed, to copy the report, to print it,
to save it or to export it to Excel.
