WebJan 19, 2024 · A lognormal distribution is a result of the variable “ x” being a product of several variables that are identically distributed. It is common in statistics that data be normally distributed for statistical testing. The lognormal distribution can be converted to a normal distribution through mathematical means and vice versa.

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.
