Simulated Data from Skin Cancer Chemoprevention Trial

This dataset, SkinCancerChemo_df, is a data frame containing simulated data mimicking the Skin Cancer Chemoprevention Trial as used in Chiou et al. (2017). It records tumor recurrence in patients who were part of the trial, which includes information on patient demographics, prior tumors, and the treatment they received. The dataset consists of 894 observations with 7 variables.

Usage

data(SkinCancerChemo_df)

Format

time

Time to event or censoring (numeric).

count

Number of tumor recurrences (numeric).

age

Age of the patient at the start of the trial (numeric).
