Graph of lognormal distribution
WebLognormal distribution of a random variable. If X is a random variable and Y=ln (X) is normally distributed, then X is said to be distributed … WebFor normalization purposes. The integral of the rest of the function is square root of 2xpi. So it must be normalized (integral of negative to positive infinity must be equal to 1 in order to define a probability density distribution). Actually, the normal distribution is based on the function exp (-x²/2). If you try to graph that, you'll see ...
