Constructors

ExponentialDistribution()

Initializes a new instance of the ExponentialDistribution class, using a StandardGenerator as underlying random number generator.

Declaration
public ExponentialDistribution()

ExponentialDistribution(Generator)

Initializes a new instance of the ExponentialDistribution class, using the specified Generator as underlying random number generator.

Declaration
public ExponentialDistribution(Generator generator)
Parameters
Type Name Description
Generator generator

A Generator object.

Properties

Lambda

Gets or sets the parameter lambda which is used for generation of exponential distributed random numbers.

Declaration
public double Lambda { get; set; }
Property Value
Type Description
System.Double

The lambda.
Remarks

Call IsValidLambda(Double) to determine whether a value is valid and therefor assignable.

Maximum

Property Value
Type Description
System.Double

The mean.
Overrides

Median

Gets the median of exponential distributed random numbers.

Declaration
public override double Median { get; }
Property Value
Type Description
System.Double

The median.
Overrides

Minimum

Gets the minimum possible value of exponential distributed random numbers.

Declaration
public override double Minimum { get; }
Property Value

System.Double

The minimum.
Overrides

Mode

Gets the mode of exponential distributed random numbers.

Declaration
public override double[] Mode { get; }
Property Value
Type Description
System.Double[]

The mode.
Overrides

Variance

Gets the variance of exponential distributed random numbers.

Declaration
public override double Variance { get; }
Property Value
Type Description
System.Double

The variance.
Overrides

Methods

IsValidLambda(Double)

Determines whether the specified value is valid for parameter Lambda.

Declaration
public bool IsValidLambda(double value)
Parameters
Type Name Description
System.Double value

The value to check.
Returns
Type Description
System.Boolean

true if value is greater than 0.0; otherwise, false.

NextDouble()

Returns a exponential distributed floating point random number.

Declaration
public override double NextDouble()
Returns
Type Description
System.Double

A exponential distributed double-precision floating point number.
