Hello, I am interested in examining an interaction between 3 latent continuous variables. Is this possible in MPlus using the xwith option? If so, what is the syntax? Thank you. 


I think you can do this usng XWITH two times. Create the interaction for two latent variables in the first XWITH and use that interaction in the second XWITH along with the third latent variable. 


Thank you for your quick response. I am using the 3way interaction term as an independent variable. Do I need to include all twoway interactions in the ON statement as I would in a regression? Thanks again for your help. 


I would do the same as in regular regression.

Dear Professors Muthens, A question about threeway latent interaction using LMS on Mplus 7.0: How to standardize the coefficient of a threeway latent interaction? Say, I have: Y= aA+bB+cC+ d(A*B)+e(A*B*C), how do I standardize e? My understanding is that to standardize the coefficient of the twoway interaction d, we can do this: d(standardized)= (sqtr of Variance of A) * (sqrt of the variance of B)/sqrt of variance of Y. So, to standardized e, can we do it this way: e(standardized)= (sqtr of Variance of A) * (sqrt of the variance of B)*(sqrt of the variance of B)/(sqrt of variance of Y). If not, how can I standardize e? Many thanks in advance! Sailor 


You should take a look at the FAQ "Latent Variable Interactions".
