LogNormal[ <Mean>, <Standard Deviation>, x ]
Creates probability density function (pdf) of log-normal distribution with parameters mean μ and standard deviation σ.
LogNormal[ <Mean>, <Standard Deviation>, x, <Boolean Cumulative> ]
If Cumulative is true, creates cumulative density function of log-normal distribution, otherwise creates pdf of log-normal distribution.
LogNormal[ <Mean>, <Standard Deviation>, <Variable Value> ]
Calculates the value of cumulative distribution function of log-normal distribution at variable value v, i.e. the probability P(X ≤ v) where X is a random variable with log-normal distribution given by parameters mean μ and standard deviation σ.
Note: Returns the probability for a given x-coordinate's value (or area under the log-normal distribution curve to the left of the given x-coordinate).
