how would the new RI-LTA approach be combined with the "profile similarity testing" procedure from Morin & Litalien (2017) [cited under the LTA topic on the "Papers" page]?
Specifically, I am wondering 1. whether the RI would be included as soon as the model contains more than a single time point (i.e., any test of profile similarity)? Or is the RI only relevant with "true" LTA models estimating transition probabilities (e.g., C2 ON C1)? 2. how an RI would be incorporated when manually assigning class probabilities (see Morin & Litalien, 2017, pp. 10-12)?
