Re: [R-sig-phylo] to log or not to log

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. Donald

Re: [R-sig-phylo] to log or not to log

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

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
