Re: [R] Exact 95% CI around the mean for LogNormal distribution

The mean of a log-Cauchy (aka log-Student's t with 1 degree of freedom) is infinite ;-) The median and other quantiles are not affected by transformations, though the mean is. If you really want anything other than a confidence interval about the mean of the logs, assuming a

Re: [R] Exact 95% CI around the mean for LogNormal distribution

This is largely a statistics question, so somewhat off topic here (see the posting guide linked below). Ergo the lack of a response yet. Therefore you *might* do better posting on the r-sig-ecology list. And now for a couple of statistics comments, which you are free to ignore of course, and

[R] Exact 95% CI around the mean for LogNormal distribution

Dear R-experts, I have used the EnvStats package and the elnorm function (p. 248). I would like to calculate the exact 95% confidence intervals around the mean, not around the meanlog. Here below my R code, how can I get the exact 95% CIs around the mean ? Many thanks. library(EnvStats)
