Baseline model in Mplus PreviousNext

is the "Chi-Square Test of Model Fit for the Baseline Model" in Mplus comparable to the "Chi-Square for Independence Model" in LISREL 8.53? I want to make sure in both software I am running the same model by comparing the baseline model's df and Chi-square value, but it seems that I heard that the baseline model in Mplus is a little different (so it can result in different CFI fit stat value). How different is it? Thanks for your advice!

Where y represents dependent variables and x represents independent variables, the Mplus baseline model is:

y with y is zero
y with x is zero
x with x is not zero

The LISREL baseline model is:

y with y is zero
y with x is zero
x with x is zero

Because the LISREL baseline model fits very poorly, model fit is exaggerated.

How about if there are two x's? Is the correlation with x1 and x2 also 0? Or they stay the same ?

"x with x is not zero" implies x1 with x2 not zero (but equal to sample covariance).
