 | Rand |
Class RandGenLogNormal generates random numbers from a lognormal
distribution.
Inheritance HierarchyNamespace: CenterSpace.NMath.Core
Assembly: NMath (in NMath.dll) Version: 7.4
SyntaxThe RandGenLogNormal type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | RandGenLogNormal | Constructs a RandGenLogNormal instance with the default underlying normal distribution. The generated deviates will follow a lognormal distribution with default mean of 1.0 and variance of 0.1. |
| RandGenLogNormal(Int32) | Constructs a seeded RandGenLogNormal instance with the default underlying normal distribution. The generated deviates will follow a lognormal distribution with default mean of 1.0 and variance of 0.1. |
| RandGenLogNormal(RandomNumberGeneratorUniformRandomNumber) | Constructs a random number generator using the given delegate as the underlying uniform random number generator. The generated deviates will follow a lognormal distribution with a mean of 1.0 and variance of 0.1. |
| RandGenLogNormal(Double, Double) | Constructs a RandGenLogNormal instance with the default underlying normal distribution. The generated deviates will follow a lognormal distribution with the specified mean and variance. |
| RandGenLogNormal(Double, Double, RandomNumberGeneratorUniformRandomNumber) | Constructs a RandGenLogNormal instance using the given delegate as the underlying uniform random number generator. The generated deviates will follow a lognormal distribution with the specified mean and variance. |
| RandGenLogNormal(Double, Double, Int32) | Constructs a seeded RandGenLogNormal instance with the default underlying normal distribution. The generated deviates will follow a lognormal distribution with the specified mean and variance. |
