I'm trying to figure out what the differences between AssocTestMM (in GENESIS library) and EMMAX are. I was told they are equivalent, but the results I'm getting from the two are slightly different. Should they match perfectly? What is the cause of the differences?

Thank you.

Hello, The results should be very similar. The first question that comes to mind is: are you using the same covariance (relationship) matrix for each software? how did you calculate it? When you say the results are slightly different, could you please elaborate? What is different? and how different is it? I wouldn't expect the numerical solutions to be *exactly *the same seeing as the solution is found through an iterative process, but I would expect them to be quite similar.
