Dear Dr. Muthen, I have a question about non-recursive model in latent class analysis.C is a latent variable with 3 nominal indicators: A1 A2 A3.U228 a dichotomous variable and one of predictors of C. Could you please let me know how I should fix my syntax? usevariables=A1 A2 A3 U228 D1 D2 D3 D4; nominal=A1 A2 A3; categorical=U228; class=c(2); Analysis: type=mixture; alhorithm=integration; Model: %overall% c on D1 D2 D3 u228; u228 on D1 D2 c; Thank you very much! yawen |

"u ON c" is not used in Mplus. Instead, the thresholds of u vary across the c classes (by default). But I think this model runs into a reciprocal interaction problem. I don't understand how a variable such as u228 can both influence the class membership probabilities and have its probability vary as a function of classes. If c is a function of u228, the u228 proportions will be different in the different c classes. |
