Hi Jarod,
In fact you can either choose a fixed root, or a draw from a multivariate
normal with the stationary covariance (random root).
I will change the name of the options in an upcoming release (and on gitHub) to
mak

Hi,
I am unclear what assumptions are being made about the root values in
mvOU, and was wondering if someone could clarify? For ease, imagine an
OU1 model where there is one optimum per trait and so theta is a vector.
Is the root value assumed to be theta, or a draw from a multivariate
normal
