ProstateSurvival_df: Prostate Cancer Survival Data

In OncoDataSets: A Comprehensive Collection of Cancer Types and Cancer-Related Datasets

Prostate Cancer Survival Data

Description

This dataset, ProstateSurvival_df, is a data frame containing survival times for two competing causes: time from prostate cancer diagnosis to death from prostate cancer, and time from prostate cancer diagnosis to death from other causes. The data set also contains information on several risk factors. The data in this data set are simulated from detailed competing risk survival curves and counts of numbers of patients per group presented in Lu-Yao et al. (2009).

Usage

Format

A data frame with 14,294 observations and 5 variables:

grade

Cancer grade categorized into 2 levels (factor).

ageGroup

Age group categorized into 4 levels (factor).

survTime

Survival time in months from prostate cancer diagnosis (integer).

status
