HI, I am relatively new to R and would appreciate some help or directions for this. I am trying to model 3 longitudinal outcomes jointly and to identify some predictors for these 3 joint outcomes (all continuous). I am trying to find some codes that I may modify to do this but cannot seem to find anything. -- View this message in context: http://r.789695.n4.nabble.com/multivariate-modeling-codes-tp4032624p4032624.html Sent from the R help mailing list archive at Nabble.com.

Not sure if this helps, but did you try Google? http://www.jstatsoft.org/v35/i09/paper http://cran.r-project.org/web/packages/lcmm/lcmm.pdf http://www.warwick.ac.uk/statsdept/useR-2011/abstracts/010411-liquetbenoit.pdf

Hi, It is not at all clear to me what type of model you are trying to fit. You could consider ?manova for a multivariate analysis of variance require(lme4) ?lmer for longitudinal regression type models or perhaps OpenMx: http://openmx.psyc.virginia.edu/ for structural equation modelling in R. Cheers, Josh

Hi: R-Bloggers picked up on this web site that contains several interesting posts re usage of R, including this one on using a Bayesian approach to multivariate mixed effects models using the MCMCglmm package: http://www.quantumforest.com/2011/11/coming-out-of-the-bayesian-closet-multivariate-version/ With multiple responses in a longitudinal study, this might be of interest to you. A similar question re multivariate response was asked a few days ago on R-sig-mixed-models, where Kevin Wright posted the above link. I'd suggest that future questions on this subject be moved to that group. HTH, Dennis
