Album: Dragonfly. Lyrics: Life has come a long way since yesterday I say. And its not the same old thing over again I say. Just do what you feel and don't you fool yourself I say. Cause I can't make you happy unless I am I say I say I. Got to be true to myself got to be true to myself.
DEFINITION of 'Log-Normal Distribution'. A statistical distribution of random variables which have a normally distributed logarithm. Log-normal distributions can model a random variable X where log(X) is normally distributed. These distributions, under multiplication and division, are self-replicating.
If you let Ï = sqrt(v + m2), then the formulas are more simply written as. Î¼ = ln(m2 / Ï), Ï2 = ln(Ï2 / m2 ) Consequently, you can specify the mean and the variance of the lognormal distribution of Y and derive the corresponding (usual) parameters for the underlying normal distribution of log(Y), as follows:
