I will conduct a Multivariate Regression with two outcome variables (Burn-out & Engagement), and 12 independent variables. In total, I have 20 parameters, and using the Rule of Thumb of at least 10 cases per parameter, this would require 200 participants.
However, I am prompted to do a power analysis. I know that this is hard (or even impossible?) in SEM for this analysis. Does anyone know whether this is possible anyway? Would the 'semPower' package be helpful?
