I have a growth curve estimated with five timepoints.
I want to know for which timepoints growth was significant.
To do this, I have run the model five times with different time scores as shown below.
I can then obtain the estimate (SE) for each time period (from 0 to 1).
I would prefer not to run five separate models - how can timepoints be evaluated within a single model in Mplus?
i s q | y1@0 y2@1 y3@2 y4@3 y5@4;
!i s q | y1@-1 y2@0 y3@1 y4@2 y5@3;
!i s q | y1@-2 y2@-1 y3@0 y4@1 y5@2;
!i s q | y1@-3 y2@-2 y3@-1 y4@0 y5@1;
!i s q | y1@-4 y2@-3 y3@-2 y4@-1 y5@0; |

| You need only use one model and then use Model Constraint to express the differences in model-estimated means (see Topic 3 of our course handouts) between each time point. |
