Cohort Helper

Group demo customers into cohorts and measure repeat-purchase behaviour.

  1. Confirm columns: agnes schema orders_demo and agnes schema customers_demo (customer_id, name, country).
  2. Repeat purchasers: agnes query "SELECT count(*) FROM (SELECT customer_id FROM orders_demo GROUP BY 1 HAVING count(*) > 1)".
  3. Cohort by country: join on customer_id and group by country, e.g. agnes query "SELECT c.country, count(DISTINCT o.customer_id) AS customers, count(*) AS orders FROM orders_demo o JOIN customers_demo c USING (customer_id) GROUP BY 1 ORDER BY 2 DESC".
  4. Summarise each cohort with its size and repeat rate.

All analysis is local against the bundled synthetic dataset.
