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.
Observe that the logarithmic function f (x) = log b x is the inverse of the exponential function g (x) = bx. It has the following properties. 1  The domain is the set of all positive real numbers. 2  f (x) = log b x is not defined for negative values of x, or for 0. (Since the logarithmic function is the inverse of the exponential function, the domain of logarithmic function is the range of exponential function, and vice versa.). 2  The function is continuous and one-to-one.
