butterfly dataset

Description

Synthetic dataset.

Usage

data(butterfly)

Format

A matrix with 15 rows and 2 columns.

Details

The butterfly dataset motivates the need for the fuzzy approach to clustering. Two clusters are clearly visible, but unit n.8 is between the two clusters, and hence its assignment is complex for standard clustering methods.

customers dataset

Description

Annual spending of a sample of consumers.

Usage

data(customers)

Format

A data.frame with 440 rows on 8 variables.

Details

The dataset is a sample of 440 customers characterized by 6 continuous variables, giving the annual spending related to different types of goods. The variables are Fresh, Milk, Grocery, Frozen, Detergents_Paper and Delicassen. Two more variables are categorical and provide information on the customer channel (Channel with 2 levels: Horeca, i.e., Hotel/Restaurant/Cafe, Retail) and the region (Region with 3 levels: Lisbon, Oporto, Other). The categorical variables should not play an active role in the clustering process, but they can be used ex-post to aid cluster interpretation.
