Three latent class variables, crossed 

Message/Author 


Is it possible to set up a model with three latent class variables, and have combinations of all of them. Something like: Model model c_1.c_2.c_3: I know that c_1.c_2 is possible (as in example 8.8 in the manual), but I wanted to extend this. In addition, I've been trying to get around this by using a larger number of classes and adding constraints, but I'm not succeeding  do you know if anyone has ever done this? Thanks, Jeremy 


Using three categorical latent variables with the . specification should work. 


Dear Linda, To follow the above question posted by Jeremy, is it possible to specify a new latent class variable which is a combination of two latent class variables? For example, if I have two latent class variables and each has two latent classes, I would like to specify a new latent class variable which has 4 classes as a crossed combination between these two LC variables. Thanks. Ping 


The simplest way is to have one latent class variable with four classes. If you have two with two classes, you can use the . formulation shown in Example 8.14.
