WebThe general theory of random variables states that if x is a random variable whose mean is μ x and variance is σ x 2, then the random variable, y, defined by y = a x + b, where a and b are constants, has mean μ y = a μ x + b and variance σ y 2 = a 2 σ x 2. You can apply this concept to get a sample of normally distributed random numbers ... WebThen a log-normal distribution is defined as the probability distribution of a random variable.
