I am VERY new to SEM and also to OpenMx and I am trying to run a very simple CFA in OpenMx, which has 1 latent factor (F1) and 3 indicators of A, B, and C with C as my scaling variable and I have a couple of questions about the output that I got:
(1) The output provides information on "Estimate", "Std. Error", "Std. Estimate", "Std. SE" and my question is: how do I derive the Std. Estimate based on the other info in the output that I got? For example, from indicator A to F1, Estimate is .6987, Std. Error is: .1245, Std. estimate is .6571, and Std. SE is .11715045. So let's say that the output didn't provide the Std. estimate. How do I obtain .6571 based on the other results?
(2) I compared the answers from OpenMx to the answers I got from Amos, and I got all identical results as far as standardized path loadings. However, in Amos, it gives me the standardized estimate for the path between C and F1, but in OpenMx, it only gives me standardized path coefficients for A to F1, and B to F1. Therefore, in my script, how do I get to specify that C is my scaling indicator and still allow OpenMx to estimate its standardized path loading just like in Amos?
Thank you so much in advance for your help on this, and please let me know if I need to clarify anything.
