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 with expectation theta, and covariance matrix equal to the
stationary covariance?
Thanks for any help,
Jarrod
