Calculates the Kaplan-Meier estimate of the survivor function, using data where the actual survival time (or time to censoring) is known.
Time Points
Observed timepoints or timepoints at which censoring took place.
Censored
Variate containing the values 0 and 1 to indicate whether the corresponding timepoint is censored (1) or not (0).
Groups
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.
Graph Options
Allows you to specify titles and control the display of the plot.
Log-cumulative hazard plot
Plots the Log-cumulative hazard against the log of the time points.
Available Data
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 on a name to copy
