Prof. Muthen I am very new to MPlus as we recently bought it. I have the following model to estimate Y1 = f(eta1) Y2 = f(eta3) Y3 = f(eta2) eta1 = g(X, eta2, eta3), where the vector Y1, Y2 and Y2 are the sets of indicator variables for the latent variable eta1, eta2 and eta3 respectively, and X is a vector of strictly exogenous variables. Our model suggests eta1 is likely to come from a multimodal distribution. I have to do a latent class analysis on eta1. My questions to you are Q1. could I fit a "latent class analysis with covariate" type model when we have continuous latent variables in the covariate vector. Q2. Could you kindly suggest me some references where they dealt situations like mine Thank you, John |

Q1. Yes - especially class-varying means of eta1 would orchestrate the multimodality. Q2. This has been looked at in the marketing lit, e.g. Jedidi, K., Jagpal. H.S. & DeSarbo, W.S. (1997). Finite-mixture structural equation models for response-based segmentation and unobserved heterogeneity. Marketing Science, 16, 39-59. |
