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 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 . |
