Hi folks, I am new to SEM and I am thinking of using SEM on a survey panel data. But I am not sure whether it makes sense to do so. So the data I have is a longitudinal one with three waves. I basically have four major questions here:
1. Whether SEM could be used with survey panel data? If yes, how could I account for the longitudinal structure of the data? For instance, I have an DV which is student's reading outcome and I have IVs such as teacher race and family SES. The mediator I have is teacher evaluated student behavior. Since all of those variables i mentioned are changing across waves except for race, how could SEM handle this?
2. What format of data should I prepare in order to use SEM? Long or wide format?
3. How to use sampling weight? I noticed an option in SEM builder and it seems I can add whatever sampling weight I have there.
4. Where can I add indirect effect using SEM builder? I didn't find any options from the left bar that allows me to add indirect effect. Is there a way for me to achieve this using SEM builder?
Thanks!
