| Nov 25, 2020 at 15:29 | comment | added | EdM | @MattFrank if the question is whether the distribution of the log(RR) is closer to normal than the distribution of the RR itself, then this answer gives one important reason. The distribution of the RR could take on some other potentially useful parametric form, but that form couldn't be close to normal unless the RR is highly positive. For closeness of the log(RR) to normal, the page you link provides some insight. | |
