Hello, I would like ask a few questions about the growth mixture with zero-inflated Poisson model and set a zero class.
(1) According to the paper (Kreuter 2007), the zero class setting in Mplus is shown as below, %c#3% ! zero class throughout [i-q@0]; [ii-qi@0]; i@0; [cage10-cage30@-15]; [cage10#1-cage30#1@-15]; Why do the intercepts set to be “-15”? Moreover, can we set the class that the score <5 instead of zero class?
(2) In Mplus, can we set the minimum sample size for each class? For example, at least 5% of the total sample is classified in each class. If not, can we set the priority for splitting new class group? For example, there are two class which class 1 and 2 have 2000 and 100 respectively. However, Mplus sometimes split class 2 instead of class 1 when classifying 3 classes analysis. So, can we set the priority to split class 1 instead of class 2 in Mplus?
