getsurv {interval} | R Documentation |
get survival values from icfit object
Description
For a vector of times, getsurv
gets the associated survival values.
The MLE is not uniquely defined for times inbetween the first and second row on the
same column of the intmap.
If there is not
a unique MLE for a specific time, then either use,
interpolation: (default), which basically finds the point on the line connecting
the two points bounding the non-unique MLE interval, or,
left: take the left side of the non-unique MLE interval (smallest value) or,
right: take the right side of the non-unique MLE interval.
Usage
getsurv(times, icfit, nonUMLE.method = "interpolation")
Arguments
times |
numeric vector of times |
icfit |
icfit object used to define the survival function |
nonUMLE.method |
character vector, either "interpolation", "left" or "right".
Method for finding survival when times element is not
at a unique MLE time. |
Value
a LIST,with elements
S |
vector of survival function values at each element of times |
times |
vector of times for which need survival function |
unique.mle |
logical denoting whether associated survival value is a unique MLE |
nonUMLE.method |
character vector describing non-unique MLE method |
