Description

Left ventricular ejection fraction in patients with malignant ventricular tachyarrhythmias including recurrence-free month and censoring.

Usage

hohnloser

Format

A data frame with 94 observations on 3 variables.

EF: ejection fraction (%).
time: recurrence-free month.
event: status indicator for time: 0 for right-censored observations and 1 otherwise.

Details

The data was used by Lausen and Schumacher (1992) to illustrate the use of maximally selected statistics.
