LogNormal Distribution
The LogNormal distribution is a continuous probability distribution. It models a broad range of random variables, whose logarithm is normally distributed.
The LogNormal distribution has two parameters:
Parameter 1 is the expected value or mean .
Parameter 2 is the standard deviation of the natural log.
The example below shows the probability density function for 3 LogNormal distributions. Each distribution has a parameter 1 value of 1.0 and a range of parameter 2 values from 0.25 to 1.0.
