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

residuals.rsaddR Documentation

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.
