Ranking the Customers

best_churn["no_of_transactions"] = group_by_customer.size()
best_churn["amount_spent"] = group_by_customer.sum()

best_churn[["no_of_transactions", "amount_spent"]].describe().loc[["min", "max"]]

How do we find out the threshold score value?

coupon = data["tran_amount"].mean() * 0.3Output - 19.4976
top_50_churned = best_churn.loc[best_churn["churned"] == 1].head(50)
