## S3 method for class 'jointModel':
ranef(object, postVar = FALSE, \dots)jointModel.TRUE the variance-covariance matrix of these estimates is also returned.
See Details for more info.postVar = TRUE, the numeric matrix has an extra attribute ``postVar".

keyword{methods}"weibull-GH-PH", "weibull-AFT-GH", "Cox-PH-GH", "spline-PH-GH" and
"piecewise-PH-GH" the ranef() method returns the posterior means (and posterior variances if
postVar = TRUE), whereas for method "ch-Laplace" it returns the posterior modes (and the inverse of
the negative of the second-order derivative of the log-posterior with respect to the random effects, if postVar = TRUE).
