What to do

From these segments' numbers. Setting buttons fill in the Build segments tab (then Build segments); merge buttons change the table below (then Save labels, no refit).
  • Worth doingS4, S5 are very small (1 to 16 snapshots)

    Under 30 snapshots, a segment's rates swing with a couple of people, and here the fit is mostly splitting off a few odd snapshots. Merge each into the segment it's most like (S4 → S2, S5 → S2). Keep one only if it's a group you specifically care about.

  • Worth doingordered: use S3, S2 as the targets on Outcomes

    S3, S2 hold 41% of ordered in 18% of the snapshots (2.2× the overall rate).

  • Fine as isUnknowns: 0.7% of snapshots

    A small unknown share means nearly everyone fits a segment, while the odd ones aren't forced in.

Name them, merge near-duplicates, or send one to unknown. Nothing is refitted.

Share of each segment's snapshots whose entity eventually had the outcome. Lift = rate ÷ overall rate.

Movement between segments

Where each entity's next snapshot lands, as a share of the row
There are 232 steps from one snapshot to the next. 77% stayed in the same segment, so people mostly keep their pattern.

Choosing the number of segments

The number of segments was fixed at 5, so there's nothing to compare.

Fixed at 5 segments, so there was nothing to compare.

The unknowns

16 snapshots (0.7%) are unknown: 0 too little history, 0 between segments, 16 fit no segment.
KindSnapshotsNearest segment
Unknown: fits no segment
Doesn't resemble any segment. Worth a look: new patterns and fraud often start here.

Boundary rules

How to recognise each segment
Together the rules agree with the model 99% of the time: good enough to use as a description.
Each segment gets its own short rules for picking it out from everyone else, in each feature's own units. Taken together, simple rules reproduce 99% of the assignments. Rules show where the lines fall, not why: use the profile above for what defines a segment. Unknowns have no rules; they come from how well a snapshot fits, not from where it sits.
S1 1 rule covering 99% of the segment
  • landingPage = / and source = Facebook and pages ≤ 11.5 · covers 99% of the segment, 100% correct
S2 2 rules covering 100% of the segment
  • landingPage is not / and source is not Direct and device is not tablet · covers 89% of the segment, 100% correct
  • landingPage is not / and source is not Direct and device = tablet · covers 11% of the segment, 100% correct
S3 1 rule covering 100% of the segment
  • source = Direct and newVisitor > 0.5 · covers 100% of the segment, 100% correct
S4 1 rule covering 100% of the segment
  • newVisitor ≤ 0.5 · covers 100% of the segment, 100% correct
S5 no clean rule: this segment overlaps others on these features

Best: K-means · device evened out (8 segments). Its target segments (S2, S3, S4) hold 77% of ordered in 20% of the training snapshots, 3.8× the overall rate, and come back at 0.96 stability when refitted.

Every setup was fitted on the same 1,828 training snapshots (1,611 people); the 20% of people held out for testing weren't used, so Outcomes can still test the winner honestly.

Settings

One segmentation with exactly these settings. To try many automatically, use Find the best.
Feature set

The inputs to segment on.

Number of segments

Search a range and let the fit decide, or fix it.

When to say "unknown"

Rather than forcing everyone into a segment.

Groups

A column such as device or caseworker that should be treated differently in this run.

Each segment count is fitted 2 times on up to 60,000 snapshots. A range of 8 counts on 20,000 snapshots takes about half a minute; "Diagonal" is several times faster.
