In another question here at Cross Validated, one user asked for the correlation of log-normal random variables.
Here's the link for the question: Correlation of log-normal random variables
The accepted answer presents an equation for the correlation between log-normal random variables Y1 e Y2 as final answer.
I'd like to find/know if there's a reference for this equation, either in an article or in a book. I have been searching for it in books and articles in my field (Operational Hydrology) but I haven't been able to find it so far.
