convert normal mean and variance to lognormal
The mean m and variance v of a lognormal random variable are functions of Âµ and Ï that can be calculated with the lognstat function. They are: m=exp(Î¼+Ï2/2)v=exp(2Î¼+Ï2)(exp(Ï2)â1) A lognormal distribution with mean m and variance v has parameters.
