ranef(object, …)
# S3 method for jmodelMult
ranef(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.

# 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)
# }
