isurvfit.object: IDP Survival Curve Object

Description Arguments See Also

Description

This class of objects is returned by the isurvfit class of functions to represent a IDP survival curve.

Objects of this class have methods for the functions print, plot.

Arguments

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.
