How to summarize umx results?

Dear umx experts,

I am new to umx. May I ask how could I get the a2,c2,e2 and their CIs from the results of umxACEv, as I did with OpenMx? And how could I calculated the genetic correlation between two phenotypes with umx? I tried the demo data and found that the summary of the estimated model only reported a1,c1,e1,a2,c2,e2, and the c in umxACEv is negative. I also tried a univariate ACE model. The cl was blank. May I ask how could I use these information to summary the results which are generally reported? Any kind suggestions would be appreciated.

best wishes,

Zhi

CIs fixed for umxACEv

Hi Zhi,
Thanks for using umx.
umxACEv was new to Boulder and I see I didn't complete the summary function (it reports "big A" not "little a")
A version is on its way to CRAN now which fixes this, or you can install from github devtools::install_github("tbates/umx")

You need to request CIs. The easiest thing is m1 = umxCI(m1, run= "yes")

then plot and summary will show these for you.
Let me know if you have any more questions or suggestions for improvements.
