Class FTestResult

The result of statistical F test is stored in this class. If the F value is closer to 1.0 than FCriticalValueOneTail, then we can't deduce that first variance is smaller than second. But if F value is bigger than 1.0, then replace the series and run the test again. Maybe second series variance is smaller than first. Note: That if the second test also fails, this doesn't automatically prove that your variances are equal.

Constructors

FTestResult()

Initializes a new instance of the FTestResult class.

Declaration

Properties

FCriticalValueOneTail

Gets critical value of F which corresponds to Alpha probability. The area under normal probability density curve of tail is equal to alpha probability.

Declaration

public double FCriticalValueOneTail { get; }

Property Value

Type	Description
System.Double	The F critical value one tail.

FirstSeriesMean

Gets first series mean value. Series represents sample from studied population.

Declaration

public double FirstSeriesMean { get; }

Property Value

Type	Description
System.Double	The first series mean.

FirstSeriesVariance

Gets first series variance. Series represents sample from studied population.

Declaration

public double FirstSeriesVariance { get; }

Property Value

Type	Description
System.Double	The first series variance.

FValue

Gets calculated F value. ( Value of normally distributed random variable with mean=0, and variance=1 ).

Declaration

public double FValue { get; }

Property Value

Type	Description
System.Double	The F value.

ProbabilityFOneTail

Gets the probability that the random variable has values at the tail, assuming that null hypothesis is true.

Declaration

public double ProbabilityFOneTail { get; }

Property Value

Type	Description
System.Double	The probability F one tail.

SecondSeriesMean

Gets second series mean value. Series represents sample from studied population.

Declaration

public double SecondSeriesMean { get; }

Property Value

Type	Description
System.Double	The second series mean.

SecondSeriesVariance

Gets second series variance. Series represents sample from studied population.

Declaration

public double SecondSeriesVariance { get; }

Property Value

Type	Description
System.Double	The second series variance.
