multivariate modeling codes

yurirouge
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.

Not sure if this helps, but did you try Google?

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
