Constructors

ErlangDistribution()

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

Declaration
public ErlangDistribution()

ErlangDistribution(Generator)

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

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

A Generator object.

Properties

Alpha

Gets or sets the parameter alpha which is used for generation of erlang distributed random numbers.

Declaration
public int Alpha { get; set; }
Property Value
Type Description
System.Int32

The alpha.
Remarks

Call IsValidAlpha(Int32) to determine whether a value is valid and therefor assignable.

Lambda

Gets or sets the parameter lambda which is used for generation of erlang 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

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

The maximum.
Overrides

Mean

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

The mean.
Overrides

Median

Gets the median of erlang 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 erlang distributed random numbers.

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

The minimum.
Overrides

Mode

Gets the mode of erlang distributed random numbers.

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

The mode.
Overrides

Variance

Gets the variance of erlang distributed random numbers.

Declaration
public override double Variance { get; }

Overrides

Methods

IsValidAlpha(Int32)

Determines whether the specified value is valid for parameter Alpha.

Declaration
public bool IsValidAlpha(int value)
Parameters
Type Name Description
System.Int32 value

The value to check.
Returns
Type Description

true if value is greater than 0; otherwise, false.

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 erlang distributed floating point random number.

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

A erlang distributed double-precision floating point number.
