TRACE: The TRACE study group of myocardial infarction

In timereg: Flexible Regression Models for Survival Data

The TRACE study group of myocardial infarction

Description

The TRACE data frame contains 1877 patients and is a subset of a data set consisting of approximately 6000 patients. It contains data relating survival of patients after myocardial infarction to various risk factors.

sTRACE is a subsample consisting of 300 patients.

tTRACE is a subsample consisting of 1000 patients.

Format

This data frame contains the following columns:

id

a numeric vector. Patient code.

status

a numeric vector code. Survival status. 9: dead from myocardial infarction, 0: alive, 7,8: dead from other causes.

time
