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.
The logarithm of x to base b, denoted log b (x) (or log b x when no confusion is possible), is the unique real number y such that b y = x. For example, log 2 64 = 6, as 64 = 2 6. The logarithm to base 10 (that is b = 10) is called the common logarithm and has many applications in science and engineering.
