Extraversion Latent change Model.pdf [6] | 262.69 KB |

Extraversion Model script.pdf [7] | 59.87 KB |

So I just started learning SEM this past year, teaching myself with some guidance from my advisor. I learned on AMOS, but I'm trying to teach myself OpenMX (just started last week).

Would anyone be willing to look over the model and script I have? Model I am trying to achieve (though I'm not sure it's entirely correct) is attached as pdf "Extraversion Latent Change Model". It is a latent change model, intercept and slope created from two latent models of extraversion (time 1 and time 2). It is not the best visual representation, but did what I could in ppt! I've also attached the script in pdf format, which I would greatly appreciate if someone would check over. It seems to mostly work except I get "Warning message:In sqrt(diag(expCov)) : NaNs produced" and fit indices are all NA.
