ranef: Extract Random Effects for Joint Models

In hadjipantelis/JSM: Semiparametric Joint Modeling of Survival and Longitudinal Data

Description

ranef is a generic function which extracts random effects from objects returned by jmodelTM() or jmodelMult().

Usage

## S3 method for class 'jmodelTM'
ranef(object, ...)
## S3 method for class 'jmodelMult'
ranef(object, ...)

Arguments

object	an object inheriting from class jmodelTM or jmodelMult.
...	additional arguments required. None is used in this method.

Value

A numeric matrix with rows denoting the subjects and columns the random effects.

Examples

## Not run: 
fitLME <- lme(proth ~ Trt * obstime, random = ~ 1 | ID, data = liver)
fitCOX <- coxph(Surv(start, stop, event) ~ Trt, data = liver, x = TRUE)
fitJT.ph <- jmodelTM(fitLME, fitCOX, liver, timeVarY = 'obstime')

# random effect for the joint model
ranef(fitJT.ph)

## End(Not run)
