Prostate cancer dataset

Description

The prostate dataset was obtained from a study carried in Le (2006). This study was conducted to evaluate the clinical usefulness of the level of acid phosphatase in blood serum (APBS) x 100 to predict whether nodal involvement is present.

Usage

data(prostate)

Format

A data frame with 53 observations on the following 2 variables.

marker

level of acid phosphatase in blood serum. Numeric vector

status

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