To we have to have that bring out diagram. Indicate both the observed reasons on bins . Latent variables beneath circles. Residual variations in both both the discover or the latent variables were going to be drivened to one double-headed arrow in the versatile for you to by itself. And if these are assumed to be connected at 1, craft 1 along path. As long parameters being believed, leave a letter or perhaps library inception to a page. To manage Amos, here is but not the straight forum for you to inquire which question - Amos tech support might be able to assist. Both the report could secured serve as played beneath OpenMx, but obviously we tend to need to know additional around the sort and the record to help assist that you.

Need more detail

Dear Erik20

If anyone here is going to help you they will need more detail than a photograph of a whiteboard. What model are you trying to fit? What are X1, X2, X3 and Y? What are H_i, Hi6 and Hi7? What is the L-shaped black piece? Why are aspects of the board obscured with what looks like lipstick? What code have you tried to use? What error message did you get?

Need better diagram!

To help you we need a better diagram. Specify the observed variables in boxes (one box per observed variable). Latent variables in circles. Residual variances on either the observed or the latent variables should be drawn with a double-headed arrow from the variable to itself. If these are assumed to be fixed at 1, write 1 on the path. If parameters to be estimated, write a letter or string beginning with a letter. If you want to use Amos, this is not the right forum to ask this question - Amos tech support might be able to help. The analysis could likely be performed in OpenMx, but obviously we need to know more about the model and the data to help you.
