Great - that answered my question. Thank you!

Hi @JoshuaHess12 ,
This was a recent addition as a result of the switch from using the sklearn SMACOF implementation of MDS to using a stochastic gradient descent implementation which was done after publication. SGD is faster, but it sometimes produces results that are rotated by 90 or 180 degrees, depending on random seed. To produce a more stable output, I rotate the output to match the classic MDS initialisation using Procrustes.
