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

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