public class LogNormal : IContinuousDistribution, IUnivariateDistribution, IDistribution
The LogNormal type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | LogNormal(Double, Double) | Initializes a new instance of the LogNormal class. The distribution will be initialized with the default random number generator. |
| LogNormal(Double, Double, Random) | Initializes a new instance of the LogNormal class. The distribution will be initialized with the default random number generator. |
Properties| Name | Description | |
|---|---|---|
 | Entropy | Gets the entropy of the log-normal distribution. |
| Maximum | Gets the maximum of the log-normal distribution. |
| Mean | Gets the mu of the log-normal distribution. |
| Median | Gets the median of the log-normal distribution. |
| Minimum | Gets the minimum of the log-normal distribution. |
| Mode | Gets the mode of the log-normal distribution. |
| Mu | Gets the log-scale (μ) (mean of the logarithm) of the distribution. |
| RandomSource | Gets or sets the random number generator which is used to draw random samples. |
| Sigma | Gets the shape (σ) (standard deviation of the logarithm) of the distribution. Range: σ ≥ 0. |
| Skewness | Gets the skewness of the log-normal distribution. |
| StdDev | Gets the standard deviation of the log-normal distribution. |
| Variance | Gets the variance of the log-normal distribution. |

| DensityLn | Computes the log probability density of the distribution (lnPDF) at x, i.e. ln(∂P(X ≤ x)/∂x). |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) |
| Estimate | Estimates the log-normal distribution parameters from sample data with maximum-likelihood. |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object) |
| GetHashCode | Serves as the default hash function. (Inherited from Object) |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| InvCDF | 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. |
| InverseCumulativeDistribution | 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. |
