Segmentation models
Definitions of groups and behavioural states for analysis or operational use.
When this is useful
A group may be useful for one question and obscure important differences for another. Its definition also determines whether people can move between groups over time.
My contribution
I define and compare groupings, examine their variation and assess whether they are useful for the intended analysis or process.

A fixed cohort of 2,000 customers moves between recency states over 90 days; each row sums to 100%, and 45.5% change state.
What it covers
- Grouping criteria and assignment method
- Fixed cohorts and changing states
- Differences within and between groups
- Stability over time and treatment of small groups
The output
Segment definitions, an assignment method and an analysis of their differences and stability.
For an enquiry, describe the question and the systems involved.
