I have intensive longitudinal data measured on a twin sample. I'd like to fit DSEM models to these data but with a three level structure  measurements within individuals within twin pairs. The documentation doesn't appear to have any examples with a three level structure. Is it possible to fit this type of model in MPlus? 


Not yet, but I don't think you need it here. Just let the two twins correspond to bivariate outcomes. 


Hi, I also have an intensive longitudinal data in which participants (level 3) completed up to 7 assessments (level 1) per day for 14 days (level 2). I'd like to use DSEM models to examine the association between X and Y (both measured at level 1) at three levels: momentary, daily, and betweenperson level. (1) Is it possible to fit such a model in Mplus 8.0? (2) Can I use the crossclassified time series analysis(example 9.38) to fit such a model? Thank you! 


You can take a look at http://statmodel.com/download/Aug1718_JH_Slides.zip part 6, page 4853 I would recommend first to do the twolevel model where you have 7*14 times of observations so the cluster variable would be individual with 98 observations in each cluster and using the tinterval command to specify the time of observation. This twolevel model can then be extended to a crossclassified model as in example 9.38.
