I recently ran a bivariate cholesky script in OpenMX and am attempting to write up my results.
The results were a bit odd - I found that the genetic correlation was negative while the shared environmental correlation was positive. The phenotypic correlation is positive. If I am understanding correctly, this means that common genetic influences that serve to increase one trait will decrease the other trait, whereas the common shared environmental influences increase both traits.
My question is - I am tying to report the proportion of the phenotypic correlation due to genetic factors and the proportion due to environmental factors. I'm getting a value of -1 something for the proportion due to genetic factors and a value over 1 for the proportion due to shared environment. A colleague was looking at my results, and I found it very difficult to explain the idea of genetic influences contributing negatively to a proportion and shared environment contributing to a proportion over 1. Is there anything I'm missing?
I don't think there's a problem with my script but just wanted to check that this profile of results seems possible. From reviewing other posts, it seems like it is (I looked over this post - https://openmx.ssri.psu.edu/thread/3969), but I just want to make sure since I'm still learning about BG and also ask specifically about reporting the proportion of the phenotypic correlation due to genes/environment in a conceptually clear manner when the genetic and environmental correlations are opposite signs.
