Re: [R] (exact) confidence bounds for lognormal parameters \mu and \sigma

Thank you, it is what I was looking for: library(fitdistrplus) x-rlnorm(100) res-mledist(x, distr=lnorm) res Anyway, the results do not provide confidence intervals, but mle estimates and the hessian matrix, whose extradiagonal elements are null... is it correct?

Sorry, probbaly it is...:blush: Krusty the Klown wrote: Anyway, the results do not provide confidence intervals, but mle estimates and the hessian matrix, whose extradiagonal elements are null... is it correct? http://www.weibull.com/LifeDataWeb/confidence_bounds_log.htm

[R] (exact) confidence bounds for lognormal parameters \mu and \sigma

Dear all, a statistical question: how can I compute exact confidence intervals for the lognormal distribution parameters? I found something only on www.weibull.com www.weibull.com . Does exist a package in R which can compute them? Thanks in advance, KTK -- View this message in context:
