Hi,
Is there a way to get the actual genetic correlation value when doing bivariate analysis.
Thanks

I meant between phenotype genetic correlation.

thanks. if both traits are from the same dataset, does it make the interpretation of the genetic correlation difficult?

It shouldn't.

Hi Jian,
To estimate confidence interval for bi-variate genetic correlation(rG), is it okay to use rG plus or minues SE? or do we need to use Fisher transformation? Thanks for your time.

95% is approximately rG plus or minus 1.96*SE. I don't think Fisher transformation is necessary here.

I'm sorry to hijack this topic. I would like to test for genetic correlation between trait A and B while adjusting for C, is this possible?
My first hunch would be to run a genetic correlation between the residuals of A~C and B for example, is this correct?

You could also fit C as a fixed covariate while estimating the genetic correlation between A and B using bivariate GREML.

Hello,
Is it possible to fit multiple GRMs when runing bivariate GREML analysis for 2 binary traits (and calculate the correlation for each variance components between the 2 traits)?
Thanks!
