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 (string) – The method used to produce the simultaneous confidence band. Only the HallWellner (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 and arcsin are implemented. 
Returns: 

lcb (arraylike) – The lower confidence limits corresponding to the points in
surv_times . 
ucb (arraylike) – The upper confidence limits corresponding to the points in
surv_times .
