I am trying to run twin model by using my own dataset. However, the MZs correlations are not twice the size of Dz correlations. In this case, can I use twin modelling in my dataset?
Example : Mz correlation for trait1: 0.6892832
Dz correlation for trait2: 0.4727187
Yes, you can.
In the case 2DZr>MZr you possibly need to model shared environment (C) in your study. AFAIK
Thanks for your reply. Even though MZ correlations are twice the size of DZ correlations for some variables, the DZ correlations are insignificant. Would happened to know, if I can still apply the twin modeling to my dataset?
