Constructors

StudentsTDistribution()

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

Declaration
public StudentsTDistribution()

StudentsTDistribution(Generator)

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

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

A Generator object.

Properties

Maximum

Gets the maximum possible value of t-distributed random numbers.

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

The maximum.
Overrides

Mean

Gets the mean value of t-distributed random numbers.

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

The mean.
Overrides

Median

Gets the median of t-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 t-distributed random numbers.

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

The minimum.
Overrides

Mode

Gets the mode of t-distributed random numbers.

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

The mode.
Overrides

Nu

Gets or sets the parameter nu which is used for generation of t-distributed random numbers.

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

The nu.
Remarks

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

Variance

Gets the variance of t-distributed random numbers.

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

The variance.
Overrides

Methods

IsValidNu(Int32)

Determines whether the specified value is valid for parameter Nu.

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

The value to check.
Returns
Type Description
System.Boolean

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

NextDouble()

Returns a t-distributed floating point random number.

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

A t-distributed double-precision floating point number.
Overrides

Reset()

Resets the Student's t-distribution, so that it produces the same random number sequence again.

Declaration
public override bool Reset()
Returns
Type Description
System.Boolean

true, if the Student's t-distribution was reset; otherwise, false.
