A Data Example to Illustrate WPC Approach.
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.
A data frame with 90 observations on the following 13 variables.
a numeric vector, indicating subject id information.
a factor, indicating three different arms, with levels
a factor, indicating whether patients receive placebo or treatment, with levels
a numeric vector, first biomarker with the value between 0 and 100
a numeric vector, second biomarker with the value between 0 and 200
a numeric vector, third biomarker with the value between 0 and 100
a numeric vector, fourth biomarker with the value between 0 and 200
a numeric vector, overall survival in days
a numeric vector, overall survival in months
a numeric vector, censor information for overall survival, 0 = alive and 1 = dead
a numeric vector, progression free survival in days
a numeric vector, progression free survival in months
a numeric vector, censor information for progression free survival, 0 = censor and 1 = event
