A Data Example to Illustrate WPC Approach.

Share:

Description

This survival data example is to illustrate WPC approach. 90 patients are randomized into three different arms, 1 placebo and 2 treatments (high dose and low dose). For each patient, four biomarkers are measured at baseline. Overall survival and progression free survival information are collected.

Format

A data frame with 90 observations on the following 13 variables.

SUBJID

a numeric vector, indicating subject id information.

TRTA

a factor, indicating three different arms, with levels HighDose LowDose Placebo

ATRT

a factor, indicating whether patients receive placebo or treatment, with levels Placebo Treatment
