Pattern of frequency of occurrence in which the logarithm of the variable follows a normal distribution. Lognormal distributions are used to describe returns calculated over periods of a year or more.
Let X be a random variable with a standard normal distribution. Then the variable Y=eX has a lognormal distribution. Example: Yearly incomes in the United States are roughly log-normally distributed. If random variable X is distributed N(m, v), then the random variable Y=eX has a lognormal distributio...
A distribution where the logarithm of the variable follows a normal distribution. Lognormal distributions are used to describe returns calculated over periods of a year or more.
