Churn in the mobile gaming field: Establishing churn definitions and measuring classification similarities

作者：

Highlights：

• Churn definition statement is highly subjective.

• This research forms four groups of churn definitions for freemium mobile games.

• Methodology for evaluating similarity of churn definitions groups is proposed.

• A modified 2-adic Jaccard similarity coefficient is established.

• Dataset from a freemium mobile game is used as an empirical implementation.
