Dear All,
I am looking for a software for doing a major axis regression taking the
non-independence due to phylogeny into account and test isometry in that
framework.
In R, phytools does a SMA/RMA using comparative methods, but it's not
MA; besides, I found a difference in df compared to SMA in smatr, and
the difference is still there even if I use a star phylogeny in
phytools, which should make phytools SMA identical to smatr SMA.
Any suggestion, please, for a comparative MA including a test for slope?
Many thanks in advance.
Cheers
Andrea
