I'm running a multivariate ACE model with raw data and matrices input, based on a version by Hermine Maes.

Changing the start value for the paths from .6 to .5 makes the c path estimates flip from positive to negative.

Am I right in assuming I can just ignore the sign, because the true estimate should be the (positive) square root of the squared path?
