Hey there,
how can I calculate the significance level (p-value) for total effects in an SEM?
I used SMSS AMOS to calculate a structural equation model (SEM). I applied the Maximum Likelihood Estimator. I get total, indirect and direct effects. However, I do not get significance levels for the total effects. Is there a way to do so? May I be able to derive the significance somehow from the direct and indirect effects?
Thank you so much for you answers!

Hello Benedict,
Bootstrap parameter estimates in AMOS are typically accompanied by CI limit estimates. See the attached Rgate post for examples.
Good luck with your work.
Hey David,
thanks a lot. I am not sure how bootstrapping integrates into my SEM. I have a big data sample. Isn't bootstrapping rather a method to work with small samples? I do not see the connection yet when looking at the slides you attached.
Cordially,
Benedict
Hello again Benedict,
Bootstrapping is quite useful regardless of sample size, as it still allows for valid and robust estimation of parameters even when all the usual assumptions can't be made regarding the data (normality, homogeneity). If you're fully content with the conformance of data to the assumptions, then you might wish to consult the AMOS user's manual (as AMOS frequently defaults to not reporting certain elements, standardized path coefficients being one such example: http://www.csun.edu/itr/downloads/docs/IBM_SPSS_Amos_User_GuideV24.pdf).
Good luck finishing your project.
