Lognormal |
public class LognormalDistribution : ContinuousDistribution
The LognormalDistribution type exposes the following members.
Name | Description | |
---|---|---|
LognormalDistribution | Initializes a new instance of the LognormalDistribution class, using a StandardGenerator as underlying random number generator. | |
LognormalDistribution(Generator) | Initializes a new instance of the LognormalDistribution class | |
LognormalDistribution(Double, Double) | Initializes a new instance of the LognormalDistribution class | |
LognormalDistribution(Double, Double, Generator) | Initializes a new instance of the LognormalDistribution class, using the specified Generator as underlying random number generator. |
Name | Description | |
---|---|---|
CanReset |
Gets a value indicating whether the random number distribution can be reset, so that it produces the same
random number sequence again.
(Inherited from Distribution) | |
Generator |
Gets or sets a Generator object that can be used as underlying random number generator.
(Inherited from Distribution) | |
Maximum |
Gets the maximum possible value of lognormal distributed random numbers.
(Overrides DistributionMaximum) | |
Mean |
Gets the mean value of lognormal distributed random numbers.
(Overrides DistributionMean) | |
Median |
Gets the median of lognormal distributed random numbers.
(Overrides DistributionMedian) | |
Minimum |
Gets the minimum possible value of lognormal distributed random numbers.
(Overrides DistributionMinimum) | |
Mode |
Gets the mode of lognormal distributed random numbers.
(Overrides DistributionMode) | |
Mu | Gets or sets the parameter mu which is used for generation of lognormal distributed random numbers. | |
Sigma | Gets or sets the parameter sigma which is used for generation of lognormal distributed random numbers. | |
Variance |
Gets the variance of lognormal distributed random numbers.
(Overrides DistributionVariance) |

CDF(Double, Double, Double) | ||
Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) | |
Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object) | |

GetType | Gets the Type of the current instance. (Inherited from Object) | |
Initialize | ||
IsValidMu | Determines whether the specified value is valid for parameter Mu. | |
IsValidSigma | Determines whether the specified value is valid for parameter Sigma. | |
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) | |
NextDouble |
Returns a lognormal distributed floating point random number.

Reset |
Resets the random number distribution, so that it produces the same random number sequence again.
(Inherited from Distribution) | |
ToString | Returns a string that represents the current object. (Inherited from Object) |
Name | Description | |
---|---|---|
generator |
Stores a Generator object that can be used as underlying random number generator.
(Inherited from Distribution) |
Return log-normal distributed random deviates with given mean and standard deviation stdev according to the density function: 2 1 (ln x - m) p (x) dx = -------------- exp( - ------------ ) dx for x > 0 m,s sqrt(2 pi x) s 2 2 s = 0 otherwise where m and s are related to the arguments mean and stdev by: 2 mean m = ln ( --------------------- ) 2 2 sqrt( stdev + mean ) 2 2 stdev + mean s = sqrt( ln( -------------- ) ) 2 mean
