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.
Logarithm. The logarithm of a number N to the base a is the exponent m to which a (base of the logarithm) must be raised in order to obtain N (denoted by log a N). Thus m = log a N if am = N. For example, log 10 100 = 2, log 2 (1/32) = â5, and log a 1 = 0 since 100 = 10 2, 1/32 = 2 â5, and1 = a 0.
