HNSCC {GEInter}

A data frame containing the TCGA head and neck squamous cell carcinoma (HNSCC) data.

Description

A data frame containing the 7 environmental (E) effects (the first 7 columns), 2000 genetic (G) effects (column 8 to column 2007), logarithm of survival time (column 2008), and censoring indicator (column 2009). All of them can be downloaded from TCGA Provisional using the R package cgdsr. See details.

Usage

data(HNSCC)

Format

A data frame with 484 rows and 2009 variables.

Details

There are seven E effects, namely alcohol consumption frequency (ACF), smoking pack years (SPY), age, gender, PN, PT, and ICD O3 site. For G effects, 2,000 gene expressions are considered. Among 484 subjects, 343 subjects have missingness in ACF and/or SPY. For G effects, we analyze mRNA gene expressions. A total of 18,409 gene expression measurements are available, then prescreening is conducted using marginal Cox models, finally, the top 2,000 genes with the smallest p-values are selected for downstream analysis.
