Dear R-sig-phylo,
When analyzing comparative data in a PCM framework, is it be appropriate to use
an AIC score to advocate for log transforming input data? ie model(data) vs
model(log(data))
I’m running a few OUwie models and it’s not entirely clear from the biology
whether or not the ‘standar
I don't think you can compare models like this for different transforms of
the dependent variable. The likelihood, etc., values are not comparable,
as your results suggest. But I am sure someone will correct me if I am
wrong!
Assuming this is some sort of regression model (i.e., you have one or
I agree with Ted. The comparison should be how the transformation affects
the distribution of the response variable. As Ted mentioned, you should
examine the behavior of the residuals to determine whether they conform to
the assumptions of the statistical analysis after transformation.

This makes sense to me too… thanks for your thoughts!
