statsmodels.duration.survfunc.SurvfuncRight.simultaneous_cb¶
-
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 : str
The method used to produce the simultaneous confidence band. Only the Hall-Wellner (hw) method is currently implemented.
transform : str
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 and arcsin 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.
