public interface SurvivalEstimateInterface

This interface defines the required methods for estimating the survival function.

Method Summary

double[][]	confidenceInterval(double alpha, double[] time, double[] censor) The confidence intervals for the survival function,
double[]	estimate(double[] time, double[] censor) The estimate of the survival function.

Method Detail

estimate

double[] estimate(double[] time,
                  double[] censor)

The estimate of the survival function.

Parameters:

time - the survival times of the patients.

censor - the censor indicators for the patients.

Returns:

the values of the estimates.

confidenceInterval

double[][] confidenceInterval(double alpha,
                              double[] time,
                              double[] censor)

The confidence intervals for the survival function,

Parameters:

alpha - the level of significance.

time - the survival times of the patients.

censor - the censor indicators for the patients.

Returns:

the confidence intervals for values of the survival function.
