I got the following problem with an LCGA (4 classes and one covariate): The output is saying that my slope for class 1 is negative (-2.627), but the graph (estimated means)for this class is showing a positive slope. I don't understand how this can be?
I am an absolute beginner working with Mplus and it would be wonderful if you could help me. Thank you very much!!
In a conditional model, a model with covariates, the intercepts of the intercept and slope growth factors are estimated. In an unconditional model, a model without covariates, the means of the intercept and slope growth factors are estimated.
