Lognormal

Base class: Distribution

Models a random variable with a normally distributed logarithm with log-mean m (with default value 0.0) and log-deviation s (with default value 1.0).

The probability density is given by,

$$f(x | m, s) = \frac{1}{sx\sqrt{2\pi}}\exp\left(-\frac{1}{2}\left(\frac{\ln(x)-m}{s}\right)^2\right).$$
