residuals.rsadd: Calculate Residuals for a "rsadd" Fit

In relsurv: Relative Survival

Calculate Residuals for a "rsadd" Fit

Description

Calculates partial residuals for an additive relative survival model.

Usage

## S3 method for class 'rsadd'
residuals(object, type = "schoenfeld", ...)

Arguments

object	an object inheriting from class rsadd, representing a fitted additive relative survival model. Typically this is the output from the rsadd function.
type	character string indicating the type of residual desired. Currently only Schoenfeld residuals are implemented.
...	other arguments.

Value

A list of the following values is returned:

res	a matrix containing the residuals for each variable.
varr	the variance for each residual
varr1	the sum of varr.
kvarr	the derivative of each residual, to be used in rs.zph function.
kvarr1	the sum of kvarr.
