- LogNormal[ <Mean>, <Standard Deviation>, x ]
- LogNormal[ <Mean>, <Standard Deviation>, x, <Boolean Cumulative>]
- LogNormal[ <Mean>, <Standard Deviation>, <Variable Value> ]
- LogNormal[ <Mean μ>, <Standard Deviation σ>, x ]
- Creates probability density function (pdf) of log-normal distribution with parameters μ, σ.
- LogNormal[ <Mean μ>, <Standard Deviation σ>, x, <Boolean Cumulative> ]
- If Cumulative is true, creates cumulative density function of LogNormal distribution, otherwise creates pdf of log-normal distribution.
- LogNormal[ <Mean μ>, <Standard Deviation σ>, <Variable Value v> ]
- Calculates the value of cumulative distribution function of log-normal distribution at v, i.e. the probability P(X≤v) where X is a random variable with log-normal distribution given by parameters μ, σ.
- 備註: 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).
CAS Syntaxes
In CAS View only following syntax is supported:
- LogNormal[ <Mean μ>, <Standard Deviation σ>, <Variable Value v>]
- Calculates the value of cumulative distribution function of log-normal distribution at v, i.e. the probability P(X≤v) where X is a random variable with log-normal distribution given by parameters μ, σ.
