# 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.
## Dataset Structure
The dataset is composed of two main CSV files:
### `purchases.csv`
| Column | Description |
|-----------|---------------------------------------------|
| users_id | Unique ID for each customer |
| date | Date of purchase (YYYY-MM-DD format) |
| cds | Number of CDs bought in a single purchase |
| amt | Total dollar amount spent in the purchase |
### `customers.csv`
| Column | Description |
|--------------|--------------------------------------------------|
| id | Customer ID (matches `users_id` in purchases) |
| zone | U.S. sales region |
| state | Customer's state |
| gender | Gender of the customer |
| age_category | Categorical label for customer's age group |
| age | Customer's age in years |
## Supported Tasks and Benchmarks
- **Customer Segmentation**
- **Churn Prediction**
- **CLV Modeling**
- **RFM Analysis**
- **Marketing Attribution**
This dataset is suitable for supervised and unsupervised learning tasks related to customer behavior analysis.
## Languages
Not language-dependent; numeric and categorical data only.
## Source Information
The CDNOW dataset was originally made publicly available as part of a research project on CLV modeling by:
> **Fader, Peter S., and Bruce GS Hardie. "Customer-Base Valuation in a Contractual Setting: The Perils of Ignoring Heterogeneity."** Marketing Science 29.1 (2010): 85-93.
It has since been widely used in textbooks and academic courses on marketing analytics, such as:
- *"Customer Centricity"* by Peter Fader
- *"Data Science for Business"* by Provost and Fawcett
