extends Object

Computes the survival curve for units under life-testing.

This example illustrates the K-M procedure. Assume 20 units are on life test and 6 failures occur at the following times: 10, 32, 56, 98, 122, and 181 hours. There were 4 working units removed from the test for other experiments at the following times: 50, 100, 125, and 150 hours. The remaining 10 working units were removed from the test at 200 hours. The K-M estimates for this life test are:

R(10) = 19/20
R(32) = 19/20 x 18/19
R(56) = 19/20 x 18/19 x 16/17
R(98) = 19/20 x 18/19 x 16/17 x 15/16
R(122) = 19/20 x 18/19 x 16/17 x 15/16 x 13/14
R(181) = 19/20 x 18/19 x 16/17 x 15/16 x 13/14 x 10/11
