	Member	Description
	FisherDistribution(Double, Double)	Instantiates a new Fisher distribution.
	DenominatorDegreesOfFreedom	Gets the number of degrees of freedom in the denominator.
	Equals(Object)	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	ExpectationValue(Func<(Of <<'(Double, Double>)>>))	Computes the expectation value of the given function. (Inherited from Distribution.)
	Finalize()()()()	Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode()()()()	Serves as a hash function for a particular type. (Inherited from Object.)
	GetRandomValue(Random)	Returns a random value. (Inherited from Distribution.)
	GetType()()()()	Gets the Type of the current instance. (Inherited from Object.)
	InverseLeftProbability(Double)	Returns the point at which the cumulative distribution function attains a given value. (Overrides Distribution..::..InverseLeftProbability(Double).)
	InverseRightProbability(Double)	Returns the point at which the right probability function attains the given value. (Overrides Distribution..::..InverseRightProbability(Double).)
	LeftProbability(Double)	Returns the cumulative probability to the left of (below) the given point. (Overrides Distribution..::..LeftProbability(Double).)
	Mean	Gets the mean of the distribution. (Overrides Distribution..::..Mean.)
	Median	Gets the median of the distribution. (Inherited from Distribution.)
	MemberwiseClone()()()()	Creates a shallow copy of the current Object. (Inherited from Object.)
	Moment(Int32)	Returns the given moment of the distribution. (Overrides Distribution..::..Moment(Int32).)
	MomentAboutMean(Int32)	Returns the given moment of the distribution, about the mean. (Overrides Distribution..::..MomentAboutMean(Int32).)
	NumeratorDegreesOfFreedom	Gets the number of degrees of freedom in the numerator.
	ProbabilityDensity(Double)	Returns the probability density at the given point. (Overrides Distribution..::..ProbabilityDensity(Double).)
	RightProbability(Double)	Return the cumulative probability to the right of (above) the given point. (Overrides Distribution..::..RightProbability(Double).)
	Skewness	Ges the skewness of the distribution. (Inherited from Distribution.)
	StandardDeviation	Gets the standard deviation of the distribution. (Inherited from Distribution.)
	Support	Gets the interval over which the distribution is nonvanishing. (Inherited from Distribution.)
	ToString()()()()	Returns a String that represents the current Object. (Inherited from Object.)
	Variance	Gets the variance of the distribution. (Overrides Distribution..::..Variance.)

Remarks

The ratio of the variances of two sets of normally distributed variables is distributed according to Fisher's F-distribution.

Many test statistics are ratios of variances and are therefore distributed according to the F-distribution. These include the F-test (FisherFTest(Sample, Sample)), the goodness-of-fit test for a multi-linear regression (LinearRegression(Int32)), and ANOVA tests (OneWayAnovaTest(IList<(Of <<'(Sample>)>>))).

The Fisher distribution is related to the Beta distribution (BetaDistribution) by a simple variable transformation.
