# Why is the log of relative risk ratio closer to normal distribution?

The sampling distribution of the $$\log(RR)$$is closer to normal than the distribution of RR, with standard error

$$SE(\log(RR)) = \sqrt{\frac{IN}{IE(IE + IN)} + \frac{CN}{CE(CE + CN)}}$$

I checked the reference, but the reference is also not very clear

There was a prior discussion here, but it also doesn't quite answer the question..

Conditions when the log of Relative Risk is approximately Normal
