Hello, I am currently working on my dissertation. I will be doing a latent growth curve model of depression over time, and looking at its association with the time-varying predictor of 'parental divorce'. I will also be running a moderation analysis looking at differences in the association between divorce and depression by sex. My question is- my dissertation committee would like me to explore if I have enough power to run the moderation analysis. I have all of the variables coded and I know the sample sizes, so it is a matter of running the power analysis. Is there a way to run a power analysis in MPLUS? Thank you very much.
