Dear Bengt & Linda, Could you help me with the following guestion (I have examined the Mplus manual for this but I'm unable to produce the figures I need). I have specified and multiple indicator growth model (three time points), and include in the overall model also two observed variables measured at T1 and T3. I would like to display regression curves from the level factor to the observed variables at T3, while controlling for the intial level of the observed variables. There is also a multigoup situation here, the variable used in the grouping obtion moderates these relations. I would produce the figures separately for the two outcome variables, both of which would contain regression curves in two groups of individuals. The multigroup situation is not a problem (except that the program aborts when I try to view estimated means), but I don't know how to specify the plot command correctly. Also, I'm guessing that the regression relation among the level and the outome variable should be included in the syntax while preparing the output to view the graphics  what exactly should be included in the syntax? Also, what would be the correct option in the graphical display for this situation? So far, I have been able to display a scatter plot of the level factor as a function of the T3 outcome variable in the two groups, but I would need the reggression curves instead (i.e., utilize the Beta values of the level factor in predicting the T3 outcome variable). I'd like to display the figures in Mplus, because I'm using the missing data option as well. Thank you so much! 


This type of graph is not available. You need to include the MODEL command if you want graphs based on the model results. 


Can you send your input and data to support@statmodel.com so we can look into the multiple group graphics problem.
