Summary function for a survexp object
Returns a list containing the values of the survival at specified times.
# S3 method for survexp summary(object, times, scale = 1, ...)
the result of a call to the
vector of times; the returned matrix will contain 1 row for each time. Missing values are not allowed.
numeric value to rescale the survival time, e.g., if the input data to
survfitwere in days,
scale = 365.25would scale the output to years.
For future methods
A primary use of this function is to retrieve survival at fixed time points, which will be properly interpolated by the function.
a list with the following components:
the estimate of survival at time t.
the timepoints on the curve.
In expected survival each subject from the data set is matched to a hypothetical person from the parent population, matched on the characteristics of the parent population. The number at risk is the number of those hypothetical subject who are still part of the calculation.
