# Dataset Card for CDNOW Dataset |
|
|
|
|
|
## Dataset Summary |
|
|
|
|
|
The **CDNOW dataset** is a well-known dataset in customer analytics and predictive modeling, especially used in the context of **Customer Lifetime Value (CLV)** estimation and **Buy Till You Die (BTYD)** models. This dataset consists of detailed transaction logs from a CD retailer (CDNOW) for a sample of customers, along with anonymized demographic data. |
|
|
|
|
|
It is often used in research and teaching materials for modeling purchasing behavior, including techniques like Pareto/NBD, BG/NBD, and Gamma-Gamma models. |
|
|
|
|
|

|
|
|
