Excellent video! Thanks for the clear clarification, really helpful

Hi, I am struggling to understand the output of the LCA, do you have a video explaining? If not, I can come up with a more specific question

[LaraSchreurs]

Thank you for this very excellent guide. As you suggest, I have labeled one variable that I have that is categorical but does not have ordered categories as nominal in the syntax. Yet, I don't really understand the output that I get here. For the ordered categorical variables I get results in probability scale which are easy to interpret but for this variable I get 'means'. Is it better to also list this variable as a categorical variable and not a nominal variable? Thank you in advance for your reply.

Thank you for your very useful video ! Considering the criteria we use to determine the right number of classes in a LCA, I was concerned by some inconsistent results in my analysis.
I am running a complex mixture model to conduct a LCA and to take into account the fact that I am using complex survey data, and although the plots of AIC, BIC, aBIC, AICC values of each of my models suggest me a two-class model, the vuong-lo-mendell-rubin likelihood ratio suggests me a three class model (p<0.05). Would have an idea of which criterion I should take into account ?

I conducted a latent class analysis, but I am not sure about the result. The probabilities of some classes were 1.000 and the p-value is also 1.00. I want to figure out the problem. Would you please advise?

Thank for your informative tutorials.

I have a question. I'm using latent transformation analysis. I need help regarding whether the LTA can use a mediating variable. to run Latent Transistion Analysis.

Could you please share a link foe the latest version of Mplus

do the variables have to have only 2 response categories? What if there are more than 2 categories within a latent variable (for example: age=<24, 24-34, >34)
