UnivariateShapiroFranciaTest Method

Performs a Shapiro-Francia test of normality on the sample.

Namespace:  Meta.Numerics.Statistics
Assembly:  Meta.Numerics (in Meta.Numerics.dll) Version: 4.1.4
Syntax
Copy
public static TestResult ShapiroFranciaTest(
	this IReadOnlyList<double> sample
)

Parameters

sample
Type: System.Collections.GenericIReadOnlyListDouble
The sample to test for normality.

Return Value

Type: TestResult
The result of the test.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IReadOnlyListDouble. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
Exceptions
ExceptionCondition
ArgumentNullExceptionsample is .
InsufficientDataExceptionThere are fewer than 16 values in the sample.
Remarks

Our current implementation requires the sample to contain at least 16 values. While the Shapiro-Francia test is perfectly well-defined for smaller samples, the parameterization of the null distribution for such small samples requires special handling that we have not yet coded.
