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.

Examples

data(slopop)
data(rdata)
fit <- rsadd(Surv(time,cens)~sex+ratetable(age=age*365,sex=sex,year=year),
       ratetable=slopop,data=rdata,int=5)
sresid <- residuals.rsadd(fit)
