| cpest {CPsurv} | R Documentation |
Shifts intervals iteratively and estimates change point at each step. Final change point is calculated by optimization over all estimations.
cpest(time, event, cpmax, intwd, cpmin, norm.riskset)
time |
Numeric vector with survival times. |
event |
Numeric vector indicating censoring status; 0 = alive (censored), 1 = dead (uncensored). If missing, all observations are assumed to be uncensored. |
cpmax |
Upper bound for estimated change point. Time period is split into intervals up to this point. Has to be an integer value. |
intwd |
Width of intervals into which the time period is split; default
is |
cpmin |
Lower bound for estimated change point; default is
|
norm.riskset |
Logical; if |
A list with estimated change point, p-values of exact binomial test, mean of p-values above estimated change point (part of regression function), lower and upper bounds of confidence intervals.
