SurvfuncRight.simultaneous_cb(alpha=0.05, method='hw', transform='log')
[source] -
Returns a simultaneous confidence band for the survival function.
Parameters: alpha : float
1 - alpha
is the desired simultaneous coverage probability for the confidence region. Currently alpha must be set to 0.05, giving 95% simultaneous intervals.method : string
The method used to produce the simultaneous confidence band. Only the Hall-Wellner (hw) method is currently implemented.
transform : string
The used to produce the interval (note that the returned interval is on the survival probability scale regardless of which transform is used). Only
log
andarcsin
are implemented.Returns: lcb : array-like
The lower confidence limits corresponding to the points in
surv_times
.ucb : array-like
The upper confidence limits corresponding to the points in
surv_times
