Syntax
The LogNormalDistribution type exposes the following members.
Constructors
| Name | Description | |
|---|---|---|
 | LogNormalDistribution |
Initializes a new instance of the LogNormalDistribution class.
The distribution will be initialized with the default
random number generator.

Properties
| Name | Description | |
|---|---|---|
 | Entropy |
Gets the entropy of the log-normal distribution.
[ILNumerics Statistics Toolbox] |
| Maximum |
Gets the maximum of the log-normal distribution.
[ILNumerics Statistics Toolbox] |
| Mean |
Gets the mu of the log-normal distribution.
[ILNumerics Statistics Toolbox] |
| Median |
Gets the median of the log-normal distribution.
[ILNumerics Statistics Toolbox] |
| Minimum |
Gets the minimum of the log-normal distribution.
[ILNumerics Statistics Toolbox] |
| Mode |
Gets the mode of the log-normal distribution.
[ILNumerics Statistics Toolbox] |
| Mu |
Gets or sets the log-scale (μ) (mean of the logarithm) of the distribution.
[ILNumerics Statistics Toolbox] |
| Sigma |
Gets or sets the shape (σ) (standard deviation of the logarithm) of the distribution. Range: σ ≥ 0.
[ILNumerics Statistics Toolbox] |
| Skewness |
Gets the skewness of the log-normal distribution.
[ILNumerics Statistics Toolbox] |
| StdDev |
Gets the standard deviation of the log-normal distribution.
[ILNumerics Statistics Toolbox] |
| Variance |
Gets the variance of the log-normal distribution.

Methods
| Name | Description | |
|---|---|---|
| CumulativeDistributionF |
Computes the cumulative distribution (CDF) of the distribution at x, i.e. p(X ≤ x)
[ILNumerics Statistics Toolbox] |
| Density |
Computes the probability density of the distribution (PDF) at x
[ILNumerics Statistics Toolbox] |
| DensityLn |
Computes the log probability density of the distribution (lnPDF) at x, i.e. ln(∂P(X ≤ x)/∂x).
[ILNumerics Statistics Toolbox] |
| InverseCumulativeDistributionF |
Computes the inverse of the cumulative distribution function (InvCDF) for the distribution
at the given probability. This is also known as the quantile or percent point function.
[ILNumerics Statistics Toolbox] |
| Samples |
Generates a sample from the log-normal distribution using the Box-Muller algorithm.
[ILNumerics Statistics Toolbox] |
| ToString |
A string representation of the distribution.
