"Log-normal" Meaning

A log-normal distribution is a probability distribution that is the result of a logarithmic transformation of a normal distribution. In other words, it is a distribution that is the same as a normal distribution after taking the logarithm of all the values. This distribution is often used to model positive-valued variables that have a skewed or asymmetrical distribution, such as wealth, income, or stock prices. It is also used in finance and economics to model the distribution of returns on investments.
