You can choose the method of estimation for the nonparametric estimates of survival probabilities, cumulative failure probabilities, hazard rates, etc.
Estimation Method
Kaplan-Meier: Choose to estimate the parameters using the Kaplan-Meier method.
Actuarial method: Choose to estimate the parameters using the actuarial method.
Specify time intervals as
0 to __ by __: Choose to use equally spaced time intervals - choose and enter numbers in the boxes. For example, 0 to 100 by 20 gives you these time intervals: 0-20, 20-40, and so on up to 80-100.
Enter endpoints of intervals: Choose to use unequally spaced time intervals and enter a series of numbers, or a column of numbers, in the box. For example, entering 0 4 6 8 10 20 30, gives you these time intervals: 0-4, 4-6, 6-8, 8-10, 10-20, and 20-30.
Estimate survival probabilities: Choose to estimate survival probabilities.
Estimate cumulative failure probabilities: Choose to estimate cumulative failure probabilities.
Confidence level: Enter a confidence level for all of the confidence intervals. The default is 95.0%.
Confidence intervals: Choose to use two-sided confidence intervals (the default) or just an upper or lower confidence bound.
