I am interested in testing whether a biometric moderation model in which genetic influences on personality vary as a function of relationship satisfaction provides a better fit to the data than a model without moderation. I was wondering if anyone knew where I could find code to do this analysis or had code they would be willing to share?

Hi Lily,

As one of the suggestions, I would maybe try to modify the model with age moderation that was once presented at the workshop in 2022 for your goal: [https://ibg.colorado.edu/cdrom2022/day3/practicalDay3.R](https://ibg.colorado.edu/cdrom2022/day3/practicalDay3.R) if your moderation variable is continious, this probably may work.
