In ICGE: Estimation of Number of Clusters and Identification of Atypical Units

Limphatic Database

Description

This lymphography domain was obtained from the University Medical Centre, Institute of Oncology, Ljubljana, Yugoslavia. Thanks go to M. Zwitter and M. Soklic for providing the data. The data are available at the UCI KDD data repository (Hettich S and Bay SD, 1999).

The data set consists of 148 instances presenting 18 different mixed attributes (1 cuantitative, 9 binaries and 9 nominals), and a class variable indicating the diagnostic. There are not missing values.

Usage
