Moments of lognormal distribution
Web2.1 Log-Normal Distribution The log-normal distribution is defined [4] as follows: consider a random variable T with region of ={ P 0< P<∞}and 𝑌=ln has a normal distribution with mean 𝜇 and variance 𝜎2. The probability distribution function of the random variable log-normal with a parameter 𝜇>0 and 𝜎>0, is as follows: WebThen a log-normal distribution is defined as the probability distribution of a random variable. X = e^ {\mu+\sigma Z}, X = eμ+σZ, where \mu μ and \sigma σ are the mean and standard deviation of the logarithm of X X, …
