Sampling at the audience ID level
Create hold-out groups to analyze the lift of your optimizations.
This procedure assumes that each cell you initially create is sampled separately.
1.
Perform one of the following steps:
In the Extract process in your flowchart, retrieve optimized contacts from the CellCode field, following instructions in
Retrieving optimized contacts by a PCT or OCT field
.
Add a Segment process to the flowchart and segment by the CellCode field, instead of extracting from the CellCode field in the Extract process.
2.
Randomly sample each cell into a target cell and a control cell.
a.
Add a Sample process to the flowchart.
b.
Connect the Extract process to the Sample process.
c.
Configure the Sample process by using
Random Sample
to create a target cell and control cell.
See the
IBM
®
Campaign
User's Guide
for additional instructions on configuring the Sample process.
3.
Connect all of the target and control cells that belong to a single package into a single contact process.
For more information about channeling multiple cells into separate contact processes, see
Including one Extract process per package
