getSCurves: Get Estimated Survival Curves from Semi-parametric Model for...

Description Usage Arguments Details Author(s)

View source: R/user_utilities.R

Description

Extracts the estimated survival curve(s) from an ic_sp or ic_np model for interval censored data.

Usage

1
getSCurves(fit, newdata = NULL)

Arguments

fit

model fit with ic_sp

newdata

data.frame containing covariates for which the survival curve will be fit to. Rownames from newdata will be used to name survival curve. If left blank, baseline covariates will be used

Details

Output will be a list with two elements: the first item will be $Tbull_ints, which is the Turnbull intervals. This is a k x 2 matrix, with the first column being the beginning of the Turnbull interval and the second being the end. This is necessary due to the representational non-uniqueness; any survival curve that lies between the survival curves created from the upper and lower limits of the Turnbull intervals will have equal likelihood. See example for proper display of this. The second item is $S_curves, or the estimated survival probability at each Turnbull interval for individuals with the covariates provided in newdata. Note that multiple rows may be provided to newdata, which will result in multiple S_curves.
