In AMOS / SPSS, default model is the JMP proposed model, & AMOS / SPSS Saturated model is the JMP unrestricted model. Please let me know if I am correct.

This is what I found from the JMP documentation for Structural Equation Models

Multivariate Methods > Structural Equation Models > Overview of Structural Equation Models

After you fit one or more models, you can compare the fitted models and two baseline models in the Model Comparison report. The baseline models are an unrestricted model and an independence model. The unrestricted model is a fully saturated model, which fits all means, variances, and covariances of the specified Model Variables without imposing any structure on the data. The independence model fits all means and variances of the specified Model Variables. All covariances among the specified Model Variables are fixed to zero, which leads to a highly restrictive model.

I know the workings. Just wanted a confirmation of nomenclature for SEM default models between SPSS & JMP. Repeating my question, Is Saturated Model (SPSS) = Unrestricted Model (JMP)? Please answer YES / NO. Thanks.

@Pradeep_Pai the short answer is yes :)
