Show you what lognormal distribution is？

A lognormal distribution is a probability distribution of a random variable whose logarithm is normally distributed. In other words, if X is a lognormally distributed random variable, then Y = ln(X) is normally distributed. The lognormal distribution is often used to model the distribution of values that are always positive, such as the size of particles in a fluid or the prices of stocks. The distribution is characterized by two parameters: the mean and the standard deviation of the logarithm of the variable. The shape of the distribution is skewed to the right, with a long tail on the positive side. The lognormal distribution is commonly used in financial modeling, risk analysis, and engineering applications.
