residuals.regrsurv: Residuals of a regression for survival data

In regr0: Building regression models

Description

Calculates residuals for uncensored observations and quartiles and random numbers according to the conditional distribution of residuals for censored observations. See Details for an explanation.

Usage

## S3 method for class 'regrsurv'
residuals(object, type = NULL, na.action=object, ...)
## S3 method for class 'regrcoxph'
residuals(object, type = NULL, na.action=object, ...)

Arguments

object	an object inheriting from classes Survreg or coxph
type	type of residuals required; NULL will become "response" for residuals.regrsurv and "CoxSnellMod" for residuals.coxph
na.action	a list with component na.action, which determines the na.action for the residual component of object
...	unused

Details

For censored observations, the conditional distribution of the survival time, given the censoring, is used to calculate quantiles, see condquant

Value

matrix with class condquant
