dataK: Observed Mortality Data of Patients with Cancer

Description

An data frame with a simulated sample of patients with a cancer and their follow-up.

Usage

data(dataK)

Format

The format is "data.frame". The names of the columns are:

sex	A numeric vector equals 1 for male and 2 for male.
age	A numeric vector with the age of the patient at the time of cancer diagnosis (baseline).
year	A numeric vector with the date of diagnosis (in date format, i.e.,
	the number of days since 1Jan60).
stade	A numeric vector with the disease stage: 1 for advanced cancer and 0 otherwise.
	according to the time. Only the dimension related to sex equals 1.
delay	A numeric vector indicating early diagnosis: 1 for delayed diagnosis and 0 otherwise.
biomarker	A numeric vector with a biomarker associated with cancer-specific mortality.
sexchara	A character vector with the patient gender: "male" or "female".
event	A numeric vector equals 1 for death and 0 for censoring.
time	A numeric vector with the follow-up time in days since the cancer diagnostic.

Details

The data frame was obtained by simulations. The French mortality tables were used for the expected mortality and a proportional hazard model with an Exponential distribution for the baseline hazard.
