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.
Logarithms: Introduction to The Relationship (page 1 of 3). Sections: Introduction to logs, Simplifying log expressions, Common and natural logs. Logarithms are the opposite of exponentials, just as subtraction is the opposite of addition and division is the opposite of multiplication. Logs undo exponentials. Technically speaking, logs are the inverses of exponentials.
