KAPLAN-MEIER SURVIVAL FUNCTION AND LIFE EXPECTANCY
Qamruz Zaman (Austria) and Karl Peter Pfeiffer (Austria)
|
Abstract: In
human and animal survival studies as well as
in the life testing experiments in the
physical sciences, Kaplan-Meier product limit
estimator (Kaplan and Meier [J. Amer. Statist.
Assoc. 53 (1958), 457-481]) plays an important
role to estimate the underlying survival
distribution which has widespread attention.
The method is very commonly used in
calculating the survival probabilities and in
comparison of curves. If the last observation
is event, then it gives the value zero and if
not then it gives a nonzero value. This paper
discussed the proposal of life expectancy
method which is based on probability. Also we
extend this method by considering the
independent and dependent diseases. The
advantage of this procedure is finally
exemplified in the analysis of Thalassaemia
data. |
