Dear R users,
I would like to estimate mu and sigma of a log-normal distribution, where I
know that the expected value is 1, as it is a normalized distribution. That
means as E(x) = exp (mu + 1/2*sigma^2) = 1 that 2*mu = -sigma^2 . Therefore
I only need to fit one parameter either sigma or mu. How could I do this in
R?
Thank you very much for your help!
