I was fitting a multivariate model with a general script. The commands didn't have errors. After I mxRun() and summary() my model, it quickly presented the summary. But the problem was that there were no -2ll, AIC, BIC, or any other fitting results, though the number of observations was rightly showed. And it seemed just summarized the dataset, like the min, max, and mean of every variables of the dataset, not the model fit. I guess the values of the variables were not input to the model. But why?
I attached the example script written by Rijsdijk here. Every steps I did were following the very script.
I am looking forward for your reply. Thank you in advance.
