In probability theory, a log-normal (or lognormal) distribution is a continuous probability distribution of a random variable whose logarithm is normally distributed. Thus, if the random variable X is log-normally distributed, then Y = ln(X) has a normal distribution. Equivalently, if Y has a normal … See more Generation and parameters Let $${\displaystyle Z}$$ be a standard normal variable, and let $${\displaystyle \mu }$$ and $${\displaystyle \sigma >0}$$ be two real numbers. Then, the distribution of the random variable See more • If $${\displaystyle X\sim {\mathcal {N}}(\mu ,\sigma ^{2})}$$ is a normal distribution, then $${\displaystyle \exp(X)\sim \operatorname {Lognormal} (\mu ,\sigma ^{2}).}$$ See more The log-normal distribution is important in the description of natural phenomena. Many natural growth processes are driven by the accumulation of many small percentage changes which become additive on a log scale. Under appropriate regularity … See more 1. ^ Norton, Matthew; Khokhlov, Valentyn; Uryasev, Stan (2024). "Calculating CVaR and bPOE for common probability distributions with application to portfolio optimization and density estimation" See more Probability in different domains The probability content of a log-normal distribution in any arbitrary domain can be computed to desired precision by first transforming the variable to normal, then numerically integrating using the ray-trace method. ( See more Estimation of parameters For determining the maximum likelihood estimators of the log-normal distribution parameters μ and σ, we can use the same procedure as for the normal distribution.
