RegisterCVintra (untransformed) [General Statistics]
Dear Helmut
I would say this is the definition rather than an assumption; (to me) CV is always given by sigma/mu. The nice thing for a log-normally distributed random variable is that in this case sigma/mu equals sqrt(exp(sigma^2)-1). So, I agree with you that it makes sense to present it as well.
Best,
Ben
❝ Does anybody know a reference supporting my – maybe too naïve – assumption?
