n |
total number of subjects in each curve.
|
time |
the time points at which the curve has a step.
|
n.risk |
the number of subjects at risk at t.
|
n.event |
the number of events that occur at time t.
|
n.censor |
the number of subjects who exit the risk set,
without an event, at time t.
(This number can be computed from the successive
values of the number at risk).
|
survUP |
the estimate of upper expectation of the survival
probability at time t+0.
|
survLOW |
the estimate of lower expectation of the survival
probability at time t+0.
|
survLOW0 |
the estimate of lower expectation of the survival
probability at time t=0. The upper expectation is always 1.
|
std.up |
the standard deviation of the upper distribution
of the survival probability.
|
std.low |
the standard deviation of the lower distribution
of the survival probability.
|
upper |
upper confidence limit for the survival curve.
|
lower |
lower confidence limit for the survival curve.
|
lower0 |
lower confidence limit for the survival curve
at t=0. The upper is always 1.
|
conf.type |
the approximation used to compute the confidence limits.
|
conf.int |
the level of the confidence limits, e.g. 90 or 95%.
|
strata |
number of elements of the time vector
corresponding to each curve.
The names of the elements are labels for the curves.
|
call |
an image of the call that produced the object.
