Hello Everyone, I am working with a comparative dataset using bat morphometrics. As part of my analysis, I want to estimate the phylogenetic signal of my variables. I understand how to do this using R. My question is more specifically about what kind of data I should be using when calculating the estimates.
For the purposes of my other analyses (linear regressions), I have log-transformed my data to meet assumptions for normality. When estimating phylogenetic signal, should I use my non-transformed, raw variables or the transformed variables? I get slightly different outputs if I run both on the same measure. My intuition is that using the raw values is more interpretable, but figured I would ask some people with more experience. Thank you for your time. -Alyson ____________________________________________________________ Alyson Brokaw M.S.
