Syntax

public class DiscreteUniformDistribution : Distribution

Remarks

The discrete uniform distribution generates only discrete numbers.
The implementation of the DiscreteUniformDistribution type bases upon information presented on Wikipedia - Uniform distribution (discrete).

Constructors

DiscreteUniformDistribution()

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

Declaration

public DiscreteUniformDistribution()

DiscreteUniformDistribution(Generator)

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

Declaration

public DiscreteUniformDistribution(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 uniformly 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.

Beta

Gets or sets the parameter beta which is used for generation of uniformly distributed random numbers.

Declaration

public int Beta { get; set; }

Property Value

Type	Description
System.Int32	The beta.

Remarks

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

Maximum

Gets the maximum possible value of uniformly distributed random numbers.

Declaration

public override double Maximum { get; }

Property Value

Type	Description
System.Double	The maximum.

Overrides

Distribution.Maximum

Mean

Gets the mean value of the uniformly distributed random numbers.

Declaration

public override double Mean { get; }

Property Value

Type	Description
System.Double	The mean.

Overrides

Distribution.Mean

Median

Gets the median of uniformly distributed random numbers.

Declaration

public override double Median { get; }

Property Value

Type	Description
System.Double	The median.

Overrides

Distribution.Median

Minimum

Gets the minimum possible value of uniformly distributed random numbers.

Declaration

public override double Minimum { get; }

Property Value

Type	Description
System.Double	The minimum.

Overrides

Distribution.Minimum

Mode

Gets the mode of the uniformly distributed random numbers.

Declaration

public override double[] Mode { get; }

Property Value

Type	Description
System.Double[]	The mode.

Overrides

Distribution.Mode

Variance

Gets the variance of uniformly distributed random numbers.

Declaration

public override double Variance { get; }

Property Value

Type	Description
System.Double	The variance.

Overrides

Distribution.Variance

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
System.Boolean	true if value is less than or equal to Beta; otherwise, false.

IsValidBeta(Int32)

Determines whether the specified value is valid for parameter Beta.

Declaration

public bool IsValidBeta(int value)

Parameters

Type	Name	Description
System.Int32	value	The value to check.

Returns

Type	Description
System.Boolean	true if value is greater than or equal to Alpha, and less than System.Int32.MaxValue; otherwise, false.

Next()

Returns a uniformly distributed random number.

Declaration

public int Next()

Returns

Type	Description
System.Int32	A geometric distributed 32-bit signed integer.

NextDouble()

Returns a uniformly distributed floating point random number.

Declaration

public override double NextDouble()

Returns

Type	Description
System.Double	A uniformly distributed double-precision floating point number.

Overrides
