portnoy_based: Confidence interval based on Portnoy (2003)

In zhimeir/cfsurvival: A package to construct predictive confidence interval for survival data

Confidence interval based on Portnoy (2003)

Description

Construct conformal predictive interval based on cox model

Usage

portnoy_based(x, c, alpha, data_fit, data_calib, weight_calib, weight_new)

Arguments

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.

Value

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.
