Melanoma dataset

Description

The melanoma dataset was obtained from Venkatram and Begg (1996). This study was conducted to assess the clinical usefulness of a clinical scoring scheme without dermoscope (CSS) used by dermatologists in order to determine if a suspicious pigmented lesion on the skin is a melanoma.

Usage

data(melanoma)

Format

A data frame with 72 observations on the following 2 variables.

X

clinical scoring scheme without dermoscope. Numerical vector.

group

true disease status (absence/presence of melanoma). Numerical vector (0=absence, 1=presence)
