Hello, I've been trying to answer a problem I have had for some months now and came across multivariate multilevel modeling. I know MPLUS and SPSS quite well but these programs could not solve this specific difficulty.
My problem: 9 correlated dependent variables (medical symptoms; categorical, 0-3), 5 measurement points, 10 time-varying covariates (life events; dichotomous, 0-1), N ~ 900. Up to 35% missing values on some variables, especially at later measurement points. My exploratory question is whether there is an interaction effect between life events and symptoms - and if so, what the effect is exactly. E.g. life event 1 could lead to more symptoms A B D whereas life event 2 could lead to more symptoms A C D and less symptoms E. My question is: would MMM in R be a viable option for this? If so, could you recommend literature?
