Dear R-users,

I'd like to announce the release of the new version of package JM (soon 
available from CRAN) for the joint modeling of longitudinal and 
time-to-event data using shared parameter models. These models are 
applicable in mainly two settings. First, when focus is in the survival 
outcome and we wish to account for the effect of an endogenous (aka 
internal) time-dependent covariate measured with error. Second, when 
focus is in the longitudinal outcome and we wish to correct for 
nonrandom dropout.

New features include:

* jointModel() with option "spline-PH-aGH" for the 'method' argument can 
now also handle competing risks settings.

* jointModel() with option "spline-PH-aGH" for the 'method' argument can 
now also handle exogenous time-dependent covariates, using the (start, 
stop] notation of coxph().

* The predict method allows now for both marginal and subject-specific 
predictions for the longitudinal outcome.

* The pseudo adaptive Gauss-Hermite rule is now used by default.

More information can be found in the corresponding help files, and 
examples at http://rwiki.sciviews.org/doku.php?id=packages:cran:jm

As always, any kind of feedback (e.g., questions, suggestions, 
bug-reports, etc.) is more than welcome.
