Construct conformal predictive interval based on cox model
pow_based(x, c, alpha, data_fit, data_calib, weight_calib, weight_new)
| x | a vector of the covariate of the test data. |
|---|---|
| alpha | a number betweeo 0 and 1, specifying the miscaverage rate. |
| data_fit | a data frame, containing the training data. |
| data_calib | a data frame, containing the calibration data. |
| r | the censoring time of the test data. |
| type | either "marginal" or "local". Determines the type of confidence interval. |
low_ci a value of the lower bound for the survival time of the test point.
includeR 0 or 1, indicating if [r,inf) is included in the confidence interval.
