Hello Drs. Muthen:
I need to find the variance of interaction coefficients as well as the covariance matrix that includes the covariance of the three-way interaction terms. As of now, Tech3 is not including the three-way interaction terms. I am using the XWITH function to define the three-way terms, and with three-way terms in the code- the output does not give me a TECH4.
Please advice.
Thanks! |

Tech3 gives variances for the estimates of the slopes for the interaction variables - those are the only parameters connnected with the interaction variables.
As for a covariance matrix for the interaction variables themselves, you can find information related to this in our FAQ document on our website:
