In icenReg: Regression Models for Interval Censored Data

Description Usage Arguments Details Author(s)

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

1	getSCurves(fit, newdata = NULL)

`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

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.
