This is more of a "Reply" to the rebuttal; the actual rebuttal is here <a href="https://www.pnas.org/content/108/42/E833" rel="nofollow">https://www.pnas.org/content/108/42/E833</a> And this is the original paper <a href="https://www.pnas.org/content/108/17/6889" rel="nofollow">https://www.pnas.org/content/108/17/6889</a><p>My two cents (as a pre-morning-coffee-biased and non-expert judge of this research) is that sample sizes are pretty small so authors shouldn't be reading too much into the "importance" of factors in logistic regression model.
