This option is not needed when the life table method is used to compute the survival estimates, since the plot of censored observations is not produced. This option is useful when only an output data set is needed. Only the number of censored and event times, plots, and test results are displayed. S specifies a plot of the estimated SDF versus time. H specifies a plot of the estimated hazard function versus time.
P specifies a plot of the estimated probability density function versus time.
Parentheses are required in specifying the plots. The test requires that a pivot for sweeping a covariance matrix be at least this number times a norm of the matrix. The default value is 1E-12. The mean survival time can be shown to be the area under the Kaplan-Meier survival curve. However, if the largest observed time in the data is censored, the area under the survival curve is not a closed area.
