Theta vs delta parameterization
Structural Equation Modeling
posted on Thursday, October 26, 2006 - 11:46 am
I am running a path analysis with two dichotomous outcomes. When I try to run the model, I get this error:
*** ERROR in Model command
The model is not supported by DELTA parameterization.
Use THETA parameterization.
1) What is the difference between theta vs. delta parameterization?
2) why won't my model run with delta parameterization?
3) how does this affect interpretation of the results?

If you look up the THETA option in the user's guide, you will find the a discussion of the Theta versus Delta parameterizations. I think this will answer your quesitons.
