Select menu: Stats | Survival Analysis | Kaplan-Meier
Calculates the Kaplan-Meier estimate of the survivor function, using data where the actual survival time (or time to censoring) is known.
- After you have imported your data, from the menu select
Stats | Survival Analysis | Kaplan-Meier.
- Fill in the fields as required then click Run.
This lists data structures appropriate to the current input field. It lists variates for specifying the data, and factors for the group. The contents will change as you move from one field to the next. Double-click a name to copy it to the current input field or type the name.
Observed time points or time points at which censoring took place.
Variate containing the values 0 and 1 to indicate whether the corresponding time point is censored (1) or not (0).
This can be used to indicate different groups whose survivor functions are to be estimated separately.
Compare survival curves using non-parametric tests
When selected, nonparametric tests comparing the different survival curves will be displayed. The tests displayed include the Log-rank, Wilcoxon (Breslow), Wilcoxon (Peto-Prentice) and Tarone-Ware tests.
Plot Kaplan-Meier estimates
Plots the Kaplan-Meier estimate against the time points.
Log-cumulative hazard plot
Plots the Log-cumulative hazard against the log of the time points.
Lets you specify titles and control the display of the plot.
