Niklas Braband, Sonja Braband (Gymnasium Neue Oberschule,, Braunschweig, Germany), Malte Braband (Technische Universit\"at,, Braunschweig, Germany)

TL;DR
This paper challenges the classical assumptions of independence and uniform distribution in the Coupon Collector's Problem, showing that in practice, these assumptions do not hold, but the classical model still provides an upper bound beneficial to collectors.
Contribution
It systematically models the sticker production process using combinatorial methods and quantifies deviations from independence, revealing practical implications for the classical model.
Findings
Assumption of independence is not fulfilled in practice.
Classical model provides an upper bound, benefiting collectors.
Deviations from randomness are advantageous for collectors.
Abstract
The solution of the classical Coupon Collector's Problem is based on the assumptions that all stickers are independently and uniformly distributed. We can prove statistically as well as analytically that in particular the assumption of independence is not fulfilled in the field. To achieve this result we have systematically modeled and analyzed the production process of the stickers by combinatorial methods. We have also derived measures for the deviation from independence. Thus the results for the classical Coupon Collector's Problem are not valid for practical applications anymore, but we can show that they constitute an a upper bound. This means in particular that in practice the deviation is advantageous for the collectors, not a fraud of the vendors. ------ Im klassischen Sammelbilderproblem wird angenommen, dass die Sammelbilder gleichverteilt und unabh\"angig sind, d. h. alle…
